Nondualism, also called non-duality, means "not two" or "one undivided without a second". It is a term and concept used to define various strands of religious and spiritual thought. It is found in a variety of Asian religious traditions and modern western spirituality, but with a variety of meanings and uses. The term may refer to:
- Advaya, the nonduality of conventional and ultimate truth in Madhyamaka Buddhism. In Buddhist Madhyamaka it means that there is no absolute, transcendent reality beyond our everyday reality, and while things exist, they are ultimately "empty" of any existence on their own. In Yogacara, it refers to the idea of nondualism of cognition and that which is cognized;
- Advaita, which states that all of the universe is one essential reality, and that all facets and aspects of the universe are ultimately an expression or appearance of that one reality. This is an ontological approach to nondualism, and asserts non-difference between Ātman (soul) and Brahman (the Absolute). This idea is best known from Advaita Vedanta, but also found in other Hindu traditions such as the Kashmir Shaivism, popular teachers like Ramana Maharshi and Nisargadatta Maharaj;
- "Nondual consciousness", the non-duality of subject and object; this can be found in modern spirituality.
The nondualism idea developed in the Vedic, post-Vedic Hindu and the Buddhist traditions. The oldest traces of nondualism in Indian thought is found as Advaita in the Brihadaranyaka Upanishad, as well as other pre-Buddhist Upanishads such as the Chandogya Upanishad. The Buddhist tradition added the teachings of śūnyatā; the two truths doctrine, the nonduality of the absolute and the relative truth, and the Yogachara notion of "mind/thought only" (citta-matra) or "representation-only" (vijñaptimātra). Vijñapti-mātra and the two truths doctrine, coupled with the concept of Buddha-nature, have also been influential concepts in the subsequent development of Mahayana Buddhism, not only in India, but also in China and Tibet, most notably the Chán (Zen) and Dzogchen traditions. In Hinduism, nondualism has more commonly become associated with the Advaita Vedanta tradition of Adi Shankara.
The western origins are situated within Western esotericism, especially Swedenborgianism, Unitarianism, Transcendentalism and the idea of religious experience as a valid means of knowledge of a transcendental reality. Universalism and Perennialism are another important strand of thought, as reflected in various strands of modern spirituality, New Age and Neo-Advaita.

... teaches that the multiplicity of the universe is reducible to one essential reality."
The main definitions are the nonduality of Atman and Brahman (Advaita), the nonduality of Absolute and relative (Advaya), and nondual consciousness.[note 1][note 2] The idea of nondualism is typically contrasted with dualism, with dualism defined as the view that the universe and the nature of existence consists of two realities, such as the God and the world, or as God and Devil, or as mind and matter, and so on.
According to Dasgupta and Mohanta, non-dualism developed in various strands of Indian thought, both Vedic and Buddhist, from the Upanishadic period onward. The oldest traces of nondualism in Indian thought may be found in the Chandogya Upanishad, which pre-dates the earliest Buddhism. Pre-sectarian Buddhism may also have been responding to the teachings of the Chandogya Upanishad, rejecting some of its Atman-Brahman related metaphysics.[note 3]
Advaya of Buddhism and Advaita of Hinduism both refer to nondualism. However, while Hinduism develops its concept of Advaita with an ontological approach, Buddhism develops Advaya through an epistemological approach. The "nondual consciousness" is a western, inclusive understanding of various strands of eastern religiosity.
Definition 1: Advaya – nonduality of the two truths
In Madhyamaka Buddhism Advaya refers to the nonduality of conventional and ultimate truth, or the relative (phenomenal) world and the Absolute, such as in samsara and nirvana. In Yogacara, it may also refer to overcoming the dichotomies of cognitum and cognition imposed by conceptual thought. Another Buddhist formulation of the Advaya concept has been as "non-two", which denies extremes such as the existence of reality and the non-existence of reality.
Madhyamaka – Non-duality of conventional and ultimate truth
In Madhyamaka-Buddhism, "Advaya" refers to the non-duality of conventional and ultimate truth. The ultimate truth is "emptiness", or non-existence of inherently existing "things", and the "emptiness of emptiness": emptiness does not in itself constitute an absolute reality. It is the Middle Way between eternalism ("things" have an inherent essence) and annihilationism or nihilism (nothing exists).[note 4] According to Murti, Advaya is that knowledge which is free of distinctions, such as "is" and "is not" extremes.
In Madhyamaka-Buddhism, "Advaya" is an epistemological approach. It is the recognition that ultimately everything is impermanent (anicca) and devoid of "self" or "essence" (anatta), and that this emptiness does not constitute an "absolute" reality in itself.[note 5].
Chinese Buddhism – Nonduality of mundane and highest reality
In Chinese Buddhism the Two truths doctrine was interpreted as an ontological teaching of three truths, states Whalen Lai, wherein "samsaric being and nirvanic emptiness as well any and all distinctions are not two". The Chinese Buddhist scholars posited that there is a third truth above the mundane truth of samsaric being and the highest truth nirvanic emptiness (sunyata). In one description, everything is posited to be simultaneously "empty, real and neither". According to Lai, most scholars of Chinese Buddhism, unlike Nagarjuna, failed to realize that the two truths were epistemic, not ontological. This mistake was identified and discussed by Jizang of Sanlun school.
Yogacara – non-duality of cognition and cognitum
The concept of adyava in Yogacara is an epistemological stance on the nature of knowledge. Early Buddhism schools such as Sarvastivada and Sautrāntika, that thrived through the early centuries of the common era, postulated a dualism, dvaya, wherein grasping (grahaka, "cognition") and the grasped (gradya, "cognitum") both are really existing. Yogacara postulates an advaya of grasping and the grasped, stating that only the mind (citta-mātra) or the representations we cognize (vijñapti-mātra),[note 6] really exist.
In Yogacara-thought, cognition is a modification of the base-consciousness, alaya-vijnana. By the reification of these modifications into separate consciousnesses, the Eighth Consciousnesses of Yogacara came into existence. In later Buddhist thought, which took an idealistic turn, the storehouse-consciousness or base-consciousness came to be seen as a pure consciousness, from which everything arises. According to the Lankavatara Sutra and the schools of Chan/Zen Buddhism, the alaya-vijnana is identical with the tathagata-garbha[note 7], and is fundamentally pure. Vijñapti-mātra, coupled with Buddha-nature or tathagatagarba, has been an influential concept in the subsequent development of Mahayana Buddhism, not only in India, but also in China and Tibet, most notable in the Chán (Zen) and Dzogchen traditions.
Definition 2: Advaita – nonduality of Atman and Brahman
The Hindu concept of Advaita refers to the idea that all of the universe is one essential reality, and that all facets and aspects of the universe is ultimately an expression or appearance of that one reality. This idea appears in different shades in various schools of Hinduism such as in Advaita Vedanta, Vishishtadvaita Vedanta (Vaishnavism), Suddhadvaita Vedanta (Vaishnavism), Shaivism and Shaktism. It implies, in Advaita Vedanta of Adi Shankara, that all of the reality is Brahman, and that the Atman (soul, self) and Brahman (ultimate unchanging reality) are one. Advaita ideas of schools within Hinduism contrasts with its Dvaita schools such as of Madhvacharya who stated that the experienced reality and God are two (dual) and distinct.
Advaita, states Murti, is the knowledge of Brahman and self-consciousness (Vijnana) without differences. The goal of Vedanta is to know the "truly real" and thus become one with it. According to Advaita Vedanta, Brahman is the highest Reality, The universe, according to Advaita philosophy, does not simply come from Brahman, it is Brahman. Brahman is the single binding unity behind the diversity in all that exists in the universe. Brahman is also that which is the cause of all changes. Brahman is the "creative principle which lies realized in the whole world".
The nondualism of Advaita, relies on the Hindu concept of Ātman which is a Sanskrit word that means "real self" of the individual, "essence",[web 3] and soul. Ātman is the first principle, the true self of an individual beyond identification with phenomena, the essence of an individual. Atman is the Universal Principle, one eternal undifferentiated self-luminous consciousness, asserts Advaita Vedanta school of Hinduism.
Advaita Vedanta philosophy considers Atman as self-existent awareness, limitless, non-dual and same as Brahman. Advaita school asserts that there is "soul, self" within each living entity which is fully identical with Brahman. This identity holds that there is One Soul that connects and exists in all living beings, regardless of their shapes or forms, there is no distinction, no superior, no inferior, no separate devotee soul (Atman), no separate God soul (Brahman). The Oneness unifies all beings, there is the divine in every being, and that all existence is a single Reality, state the Advaita Vedantins. The nondualism concept of Advaita Vedanta asserts that each soul is non-different from the infinite Brahman.
Definition 3: Nondual consciousness
Nondualism as a modern spiritual movement is a Universalist or Perennialist, and essentialist approach, in western spirituality. It blends Asian religions and philosophies with the Perennial philosophy, attempting to transcend the fundamental differences between advaya and advaita. Various traditions are seen as grounded in a similar non-dual experience, which is expressed in different ways by different traditions.[note 8]
The idea of a "nondual consciousness" has gained attraction and popularity in western spirituality and New Age-thinking. It is recognized in the Asian traditions, but also in western and Mediterranean religious traditions, and in western philosophy.
"Advaita" (अद्वैत) is from Sanskrit roots a, not; dvaita, dual, is usually translated as "nondualism", "nonduality" and "nondual". The term "nondualism" and the term "advaita" from which it originates are polyvalent terms. The English word's origin is the Latin duo meaning "two" prefixed with "non-" meaning "not".
"Advaya" (अद्वय) is also a Sanskrit word that means "identity, unique, not two, without a second".
One of the earliest usage of the word Advaita is found in verse 4.3.32 of the Brihadaranyaka Upanishad (~800 BCE), and in verses 7 and 12 of the Mandukya Upanishad (variously dated to have been composed between 500 BCE to 200 CE). The term appears in the Brihadaranyaka Upanishad in the section with a discourse of the oneness of Atman and Brahman, as follows:
An ocean is that one seer, without any duality [Advaita]; this is the Brahma-world, O King. Thus did Yajnavalkya teach him. This is his highest goal, this is his highest success, this is his highest world, this is his highest bliss. All other creatures live on a small portion of that bliss.
The English term "nondual" was also informed by early translations of the Upanishads in Western languages other than English from 1775. These terms have entered the English language from literal English renderings of "advaita" subsequent to the first wave of English translations of the Upanishads. These translations commenced with the work of Müller (1823–1900), in the monumental Sacred Books of the East (1879).
Advaya – nonduality of the two truths
The Advaya concept refers to the "non-two" understanding of reality. It has its origins in Madhyamaka-thought, which is built on earlier Buddhist thought, and expressed in the two truths doctrine. In Nagarjuna's interpretation it is the non-duality of conventional and ultimate truth, or the overcoming of dichotomies such as that between samsara (conditioned or relative reality, rebirth) and nirvana (unconditioned and absolute reality, liberation). This idea was further developed and re-interpreted in Chinese Buddhism, where the two truths doctrine came to refer to the nonduality of nirvana and samsara, re-incorporating essentialist notions.
Madhyamaka – nonduality of conventional and ultimate truth
The distinction between the two truths (satyadvayavibhāga) was fully expressed by the Madhyamaka-school. Madhyamaka, also known as Śūnyavāda, refers primarily to a Mahāyāna Buddhist school of philosophy founded by Nāgārjuna.
In Madhyamaka, the two truths refer to conventional and ultimate truth. Conventionally, "things" exist, but ultimately, they are "empty" of any existence on their own, as described in Nāgārjuna's Mūlamadhyamakakārikā:
The Buddha's teaching of the Dharma is based on two truths: a truth of worldly convention and an ultimate truth. Those who do not understand the distinction drawn between these two truths do not understand the Buddha's profound truth. Without a foundation in the conventional truth the significance of the ultimate cannot be taught. Without understanding the significance of the ultimate, liberation is not achieved.[note 10]
"Emptiness" is a consequence of pratītyasamutpāda (dependent arising), the teaching that no dharma ("thing") has an existence of its own, but always comes into existence in dependence on other dharmas. According to Madhyamaka all phenomena are empty of "substance" or "essence" (Sanskrit: svabhāva) because they are dependently co-arisen. Likewise it is because they are dependently co-arisen that they have no intrinsic, independent reality of their own. Madhyamaka also rejects the existence of an absolute reality or Self. Ultimately, "absolute reality" is not an absolute, or the non-duality of a personal self and an absolute Self, but the deconstruction of such reifications.
It also means that there is no "transcendental ground," and that "ultimate reality" has no existence of its own, but is the negation of such a transecendental reality, and the impossibility of any statement on such an ultimately existing transcendental reality: it is no more than a fabrication of the mind.[web 4] Susan Kahn further explains:
Ultimate truth does not point to a transcendent reality, but to the transcendence of deception. It is critical to emphasize that the ultimate truth of emptiness is a negational truth. In looking for inherently existent phenomena it is revealed that it cannot be found. This absence is not findable because it is not an entity, just as a room without an elephant in it does not contain an elephantless substance. Even conventionally, elephantlessness does not exist. Ultimate truth or emptiness does not point to an essence or nature, however subtle, that everything is made of.[web 5]
The later Madhyamikas, states Yuichi Kajiyama, developed the Advaya definition as a means to Nirvikalpa-Samadhi by suggesting that "things arise neither from their own selves nor from other things, and that when subject and object are unreal, the mind, being not different, cannot be true either; thereby one must abandon attachment to cognition of nonduality as well, and understand the lack of intrinsic nature of everything". Thus, the Buddhist nondualism or Advaya concept became a means to realizing absolute emptiness.
Yogācāra (Sanskrit; literally: "yoga practice"; "one whose practice is yoga") is an influential school of Buddhist philosophy and psychology emphasizing phenomenology and (some argue) ontology through the interior lens of meditative and yogic practices. It developed within Indian Mahāyāna Buddhism in about the 4th century CE.
According to Kochumuttom, Yogacara is a realistic pluralism. It does not deny the existence of individual beings, but denies the following:
1. That the absolute mode of reality is consciousness/mind/ideas,
2. That the individual beings are transformations or evolutes of an absolute consciousness/mind/idea,
3. That the individual beings are but illusory appearances of a monistic reality.
Vijñapti-mātra, "consciousness-only" or "representation-only" is one of the main features of Yogācāra philosophy. It is often used interchangeably with the term citta-mātra, but they have different meanings. The standard translation of both terms is "consciousness-only" or "mind-only." Several modern researchers object to this translation, and the accompanying label of "absolute idealism" or "idealistic monism". A better translation for vijñapti-mātra is representation-only.
Vijñapti-mātra then means "mere representation of consciousness":
[T]he phrase vijñaptimātratā-vāda means a theory which says that the world as it appears to the unenlightened ones is mere representation of consciousness. Therefore, any attempt to interpret vijñaptimātratā-vāda as idealism would be a gross misunderstanding of it.
The term vijñapti-mātra replaced the "more metaphysical" term citta-mātra used in the Lankavatara Sutra. The Lankavatara Sutra "appears to be one of the earliest attempts to provide a philosophical justification for the Absolutism that emerged in Mahayana in relation to the concept of Buddha". It uses the term citta-mātra, which means properly "thought-only". By using this term it develops an ontology, in contrast to the epistemology of the term vijñapti-mātra. The Lankavatara Sutra equates citta and the absolute. According to Kochumuttom, this is not the way Yogacara uses the term vijñapti:
[T]he absolute state is defined simply as emptiness, namely the emptiness of subject–object distinction. Once thus defined as emptiness (sunyata), it receives a number of synonyms, none of which betray idealism.
The Yogācārins defined three basic modes by which we perceive our world. These are referred to in Yogācāra as the three natures of perception. They are:
- Parikalpita (literally, "fully conceptualized"): "imaginary nature", wherein things are incorrectly comprehended based on conceptual construction, through attachment and erroneous discrimination.
- Paratantra (literally, "other dependent"): "dependent nature", by which the correct understanding of the dependently originated nature of things is understood.
- Pariniṣpanna (literally, "fully accomplished"): "absolute nature", through which one comprehends things as they are in themselves, uninfluenced by any conceptualization at all.
Also, regarding perception, the Yogācārins emphasized that our everyday understanding of the existence of external objects is problematic, since in order to perceive any object (and thus, for all practical purposes, for the object to "exist"), there must be a sensory organ as well as a correlative type of consciousness to allow the process of cognition to occur.
Vijñapti-mātra and the two truths doctrine, as understood in Chinese Buddhism, are closely linked to Buddha-nature. Those teachings have had a profound influence on Mahayana Buddhism, not only in India, but also in China and Tibet, most notably the Chán (Zen) and Dzogchen traditions. They may be related to an archaic form of Buddhism which is close to Brahmanical beliefs, elements of which are preserved in the Nikayas, and survived in the Mahayana tradition. Contrary to popular opinion, the Theravada and Mahayana traditions may be "divergent, but equally reliable records of a pre-canonical Buddhism which is now lost forever." The Mahayana tradition may have preserved a very old, "pre-Canonical" tradition, which was largely, but not completely, left out of the Theravada-canon.
The Buddhist teachings on the Buddha-nature may be regarded as a form of nondualism. Buddha-nature is the essential element that allows sentient beings to become Buddhas. The term, Buddha nature, is a translation of the Sanskrit coinage, 'Buddha-dhātu', which seems first to have appeared in the Mahayana Mahaparinirvana Sutra, where it refers to 'a sacred nature that is the basis for [beings'] becoming buddhas.' The term seems to have been used most frequently to translate the Sanskrit "Tathāgatagarbha". The Sanskrit term "tathāgatagarbha" may be parsed into tathāgata ("the one thus gone", referring to the Buddha) and garbha ("womb").[note 11] The tathagatagarbha, when freed from avidya ("ignorance"), is the dharmakaya, the Absolute.
Chinese Buddhism – nonduality of mundane and highest reality
Chinese Buddhism evolved over time. Before 400 CE, states Lai, the Chinese understood the Buddhist doctrine to be that "karmic rebirth entailed the transmigration of soul". It was monk Mindu who understood that the Buddha taught a no soul doctrine, and he tried to explain this to his Buddhist sangha, but was vilified for denying the existence of soul. Mindu's ideas, however, began a momentum that led to the emergence of six prajna schools in the 4th and 5th century CE. In the 6th century CE it became clear that anatman and sunyata are central Buddhist teachings, which make the postulation of an eternal self problematic.
Another point of confusion was the Two truths doctrine of Madhyamaka, the mundane truth and the highest truth. Chinese thinking took this to refer to two ontological truths: reality exists at two levels, the mundane level of samsara and the highest level of nirvana emptiness. But in Madhyamaka these are two epistemological truths, two different ways to look at reality. The early Chinese scholars supposed that there is an essential truth above the two truths, which unites both these. This three truths doctrine was different from a similarly named doctrine of Yogacara and Indian Buddhism.
The Huayan school or Flower Garland is a tradition of Mahayana Buddhist philosophy that flourished in China during the Tang period particularly with Fazang (~700 CE). It is based on the Sanskrit Flower Garland Sutra (S. Avataṃsaka Sūtra, C. Huayan Jing) and on a lengthy Chinese interpretation of it, the Huayan Lun. The name Flower Garland is meant to suggest the crowning glory of profound understanding. Huayan teaches the Four Dharmadhatu, four ways to view reality:
- All dharmas are seen as particular separate events;
- All events are an expression of the absolute;
- Events and essence interpenetrate;
- All events interpenetrate.
The Buddha-nature and Yogacara philosophies have had a strong influence on Chán and Zen. The teachings of Zen are expressed by a set of polarities: Buddha-nature – sunyata; absolute-relative; sudden and gradual enlightenment.
The Lankavatara-sutra, a popular sutra in Zen, endorses the Buddha-nature and emphasizes purity of mind, which can be attained in gradations. The Diamond-sutra, another popular sutra, emphasizes sunyata, which "must be realized totally or not at all". The Prajnaparamita Sutras emphasize the non-duality of form and emptiness: form is emptiness, emptiness is form, as the Heart Sutra says. According to Chinul, Zen points not to mere emptiness, but to suchness or the dharmadhatu.
The idea that the ultimate reality is present in the daily world of relative reality fitted into the Chinese culture which emphasized the mundane world and society. But this does not explain how the absolute is present in the relative world. This question is answered in such schemata as the Five Ranks of Tozan and the Oxherding Pictures.
The continuous pondering of the break-through kōan (shokan) or Hua Tou, "word head", leads to kensho, an initial insight into "seeing the (Buddha-)nature. According to Hori, a central theme of many koans is the "identity of opposites", and point to the original nonduality. Victor Sogen Hori describes kensho, when attained through koan-study, as the absence of subject–object duality. The aim of the so-called break-through koan is to see the "nonduality of subject and object",  in which "subject and object are no longer separate and distinct."
Zen Buddhist training does not end with kenshō. Practice is to be continued to deepen the insight and to express it in daily life, to fully manifest the nonduality of absolute and relative. To deepen the initial insight of kensho, shikantaza and kōan-study are necessary. This trajectory of initial insight followed by a gradual deepening and ripening is expressed by Linji Yixuan in his Three Mysterious Gates, the Four Ways of Knowing of Hakuin, the Five Ranks, and the Ten Ox-Herding Pictures which detail the steps on the Path.
Essence-function in Korean Buddhism
The polarity of absolute and relative is also expressed as "essence-function". The absolute is essence, the relative is function. They can't be seen as separate realities, but interpenetrate each other. The distinction does not "exclude any other frameworks such as neng-so or 'subject-object' constructions", though the two "are completely different from each other in terms of their way of thinking". In Korean Buddhism, essence-function is also expressed as "body" and "the body's functions". A metaphor for essence-function is "a lamp and its light", a phrase from the Platform Sutra, where Essence is lamp and Function is light.
Tantra is a religious tradition that originated in India in the middle of the first millennium CE, and has been practiced by Buddhists, Hindus and Jains throughout south and southeast Asia. It views humans as a microcosmos which mirrors the macrocosmos. Its aim is to gain access to the energy or enlightened consciousness of the godhead or absolute, by embodying this energy or consciousness through rituals. It views the godhead as both transcendent and immanent, and views the world as real, and not as an illusion:
Rather than attempting to see through or transcend the world, the practitioner comes to recognize "that" (the world) as "I" (the supreme egoity of the godhead): in other words, s/he gains a "god's eye view" of the universe, and recognizes it to be nothing other than herself/himself. For East Asian Buddhist Tantra in particular, this means that the totality of the cosmos is a "realm of Dharma", sharing an underlying common principle.
Shentong and rangtong
In Tibetan Buddhism, the essentialist position is represented by shentong, while the nominalist, or non-essentialist position, is represented by rangtong.
Shentong is a philosophical sub-school found in Tibetan Buddhism. Its adherents generally hold that the nature of mind, the substratum of the mindstream, is "empty" (Wylie: stong) of "other" (Wylie: gzhan), i.e., empty of all qualities other than an inherently existing, ineffable nature. Shentong has often been incorrectly associated with the Cittamātra (Yogacara) position, but is in fact also Madhyamaka, and is present primarily as the main philosophical theory of the Jonang school, although it is also taught by the Sakya and Kagyu schools. According to Shentongpa (proponents of shentong), the emptiness of ultimate reality should not be characterized in the same way as the emptiness of apparent phenomena because it is prabhāśvara-saṃtāna, or "luminous mindstream" endowed with limitless Buddha qualities. It is empty of all that is false, not empty of the limitless Buddha qualities that are its innate nature.
The contrasting rangtong view, of the followers of Prasaṅgika Mādhyamaka, is that all phenomena are sunyata, empty of self-nature, and that this "emptiness" is itself only a qualification, not a concretely existing "absolute" reality. This position is associated with the Madhyamaka school, which dominates both Mahayana and Vajrayana Buddhism.
Dzogchen is concerned with the "natural state" and emphasizes direct experience. The state of nondual awareness is called rigpa. This primordial nature is clear light, unproduced and unchanging, free from all defilements. Through meditation, the Dzogchen practitioner experiences that thoughts have no substance. Mental phenomena arise and fall in the mind, but fundamentally they are empty. The practitioner then considers where the mind itself resides. Through careful examination one realizes that the mind is emptiness.
Karma Lingpa (1326–1386) revealed "Self-Liberation through seeing with naked awareness" (rigpa ngo-sprod,[note 12]) which is attributed to Padmasambhava.[note 13] The text gives an introduction, or pointing-out instruction (ngo-spro), into rigpa, the state of presence and awareness. In this text, Karma Lingpa writes the following regarding the unity of various terms for nonduality:
With respect to its having a name, the various names that are applied to it are inconceivable (in their numbers).
Some call it "the nature of the mind" or "mind itself."
Some Tirthikas call it by the name Atman or "the Self."
The Sravakas call it the doctrine of Anatman or "the absence of a self."
The Chittamatrins call it by the name Chitta or "the Mind."
Some call it the Prajnaparamita or "the Perfection of Wisdom."
Some call it the name Tathagata-garbha or "the embryo of Buddhahood."
Some call it by the name Mahamudra or "the Great Symbol."
Some call it by the name "the Unique Sphere."
Some call it by the name Dharmadhatu or "the dimension of Reality."
Some call it by the name Alaya or "the basis of everything."
And some simply call it by the name "ordinary awareness."[note 14]
Advaita – identity of Atman and the Absolute
"Advaita" refers to nondualism, non-distinction between realities, the oneness of Atman and Brahman, as in Vedanta, Shaktism and Shaivism. Although the term is best known from the Advaita Vedanta school of Adi Shankara, "advaita" is used in treatises by numerous medieval era Indian scholars, as well as modern schools and teachers.[note 15]
Several schools of Vedanta teach a form of nondualism. The best-known is Advaita Vedanta, but other nondual Vedanta schools also have a significant influence and following, such as Vishishtadvaita Vedanta and Shuddhadvaita, both of which are bhedabheda.
The nonduality of the Advaita Vedantins is of the identity of Brahman and the Atman. Advaita has become a broad current in Indian culture and religions, influencing subsequent traditions like Kashmir Shaivism.
The oldest surviving manuscripts on Advaita Vedanta is by Gauḍapāda (6th century CE), who has traditionally been regarded as the teacher of Govinda bhagavatpāda and the grandteacher of Shankara. Advaita is best known from the Advaita Vedanta tradition of Adi Shankara, who states that Brahman is pure Being, Consciousness and Bliss (Sat-cit-ananda).
Advaita Vedanta – Three levels of reality
- Pāramārthika (paramartha, absolute), the Reality that is metaphysically true and ontologically accurate. It is the state of experiencing that "which is absolutely real and into which both other reality levels can be resolved". This experience can't be sublated (exceeded) by any other experience.
- Vyāvahārika (vyavahara), or samvriti-saya, consisting of the empirical or pragmatic reality. It is ever-changing over time, thus empirically true at a given time and context but not metaphysically true. It is "our world of experience, the phenomenal world that we handle every day when we are awake". It is the level in which both jiva (living creatures or individual souls) and Iswara are true; here, the material world is also true.
- Prāthibhāsika (pratibhasika, apparent reality, unreality), "reality based on imagination alone". It is the level of experience in which the mind constructs its own reality. A well-known example is the perception of a rope in the dark as being a snake.
Similarities and differences with Buddhism
In any event a close relationship between the Mahayana schools and Vedanta did exist, with the latter borrowing some of the dialectical techniques, if not the specific doctrines, of the former.
Advaita Vedanta is related to Madhyamaka via Gaudapda, who took over the Buddhist doctrine that ultimate reality is pure consciousness (vijñapti-mātra). Shankara harmonised Gaudapada's ideas with the Upanishadic texts, and provided an orthodox hermeneutical basis for heterodox Buddhist phenomology.
Gaudapada adopted the Buddhist concept of ultimate reality is pure consciousness (vijñapti-mātra). The Buddhist term is often used interchangeably with the term citta-mātra, but they have different meanings. The standard translation of both terms is "consciousness-only" or "mind-only." Advaita Vedanta has been called "idealistic monism" by scholars, but some disagree with this label. Another concept found in both Madhyamaka Buddhism and Advaita Vedanta is Ajativada ("ajāta"), which Gaudapada adopted from Nagarjuna's philosophy.[note 16] Gaudapada "wove [both doctrines] into a philosophy of the Mandukaya Upanisad, which was further developed by Shankara.[note 17]
Michael Comans states there is a fundamental difference between Buddhist thought and that of Gaudapada, in that Buddhism has as its philosophical basis the doctrine of Dependent Origination according to which "everything is without an essential nature (nissvabhava), and everything is empty of essential nature (svabhava-sunya)", while Gaudapada does not rely on this principle at all. Gaudapada's Ajativada is an outcome of reasoning applied to an unchanging nondual reality according to which "there exists a Reality (sat) that is unborn (aja)" that has essential nature (svabhava), and this is the "eternal, fearless, undecaying Self (Atman) and Brahman". Thus, Gaudapada differs from Buddhist scholars such as Nagarjuna, states Comans, by accepting the premises and relying on the fundamental teaching of the Upanishads. Among other things, Vedanta school of Hinduism holds the premise, "Atman exists, as self evident truth", a concept it uses in its theory of nondualism. Buddhism, in contrast, holds the premise, "Atman does not exist (or, An-atman) as self evident".
Mahadevan suggests that Gaudapada adopted Buddhist terminology and adapted its doctrines to his Vedantic goals, much like early Buddhism adopted Upanishadic terminology and adapted its doctrines to Buddhist goals; both used pre-existing concepts and ideas to convey new meanings. Dasgupta and Mohanta note that Buddhism and Shankara's Advaita Vedanta are not opposing systems, but "different phases of development of the same non-dualistic metaphysics from the Upanishadic period to the time of Sankara."
Vishishtadvaita Vedanta is another main school of Vedanta and teaches the nonduality of the qualified whole, in which Brahman alone exists, but is characterized by multiplicity. It can be described as "qualified monism," or "qualified non-dualism," or "attributive monism."
According to this school, the world is real, yet underlying all the differences is an all-embracing unity, of which all "things" are an "attribute." Ramanuja, the main proponent of Vishishtadvaita philosophy contends that the Prasthana Traya ("The three courses") – namely the Upanishads, the Bhagavad Gita, and the Brahma Sutras – are to be interpreted in a way that shows this unity in diversity, for any other way would violate their consistency.
Vedanta Desika defines Vishishtadvaita using the statement: Asesha Chit-Achit Prakaaram Brahmaikameva Tatvam – "Brahman, as qualified by the sentient and insentient modes (or attributes), is the only reality."
Neo-Vedanta, also called "neo-Hinduism" is a modern interpretation of Hinduism which developed in response to western colonialism and orientalism, and aims to present Hinduism as a "homogenized ideal of Hinduism" with Advaita Vedanta as its central doctrine.
Neo-Vedanta, as represented by Vivekananda and Radhakrishnan, is indebted to Advaita vedanta, but also reflects Advaya-philosophy. A main influence on neo-Advaita was Ramakrishna, himself a bhakta and tantrika, and the guru of Vivekananda. According to Michael Taft, Ramakrishna reconciled the dualism of formlessness and form. Ramakrishna regarded the Supreme Being to be both Personal and Impersonal, active and inactive:
When I think of the Supreme Being as inactive – neither creating nor preserving nor destroying – I call Him Brahman or Purusha, the Impersonal God. When I think of Him as active – creating, preserving and destroying – I call Him Sakti or Maya or Prakriti, the Personal God. But the distinction between them does not mean a difference. The Personal and Impersonal are the same thing, like milk and its whiteness, the diamond and its lustre, the snake and its wriggling motion. It is impossible to conceive of the one without the other. The Divine Mother and Brahman are one.
Radhakrishnan acknowledged the reality and diversity of the world of experience, which he saw as grounded in and supported by the absolute or Brahman.[web 7][note 18] According to Anil Sooklal, Vivekananda's neo-Advaita "reconciles Dvaita or dualism and Advaita or non-dualism":
The Neo-Vedanta is also Advaitic inasmuch as it holds that Brahman, the Ultimate Reality, is one without a second, ekamevadvitiyam. But as distinguished from the traditional Advaita of Sankara, it is a synthetic Vedanta which reconciles Dvaita or dualism and Advaita or non-dualism and also other theories of reality. In this sense it may also be called concrete monism in so far as it holds that Brahman is both qualified, saguna, and qualityless, nirguna.
Radhakrishnan also reinterpreted Shankara's notion of maya. According to Radhakrishnan, maya is not a strict absolute idealism, but "a subjective misperception of the world as ultimately real."[web 7] According to Sarma, standing in the tradition of Nisargadatta Maharaj, Advaitavāda means "spiritual non-dualism or absolutism", in which opposites are manifestations of the Absolute, which itself is immanent and transcendent:
All opposites like being and non-being, life and death, good and evil, light and darkness, gods and men, soul and nature are viewed as manifestations of the Absolute which is immanent in the universe and yet transcends it.
Kashmir Shaivism is a school of Śaivism, described by Abhinavagupta[note 19] as "paradvaita", meaning "the supreme and absolute non-dualism".[web 8] It is categorized by various scholars as monistic idealism (absolute idealism, theistic monism, realistic idealism, transcendental physicalism or concrete monism).
Kashmir Saivism is based on a strong monistic interpretation of the Bhairava Tantras and its subcategory the Kaula Tantras, which were tantras written by the Kapalikas. There was additionally a revelation of the Siva Sutras to Vasugupta. Kashmir Saivism claimed to supersede the dualistic Shaiva Siddhanta. Somananda, the first theologian of monistic Saivism, was the teacher of Utpaladeva, who was the grand-teacher of Abhinavagupta, who in turn was the teacher of Ksemaraja.
The philosophy of Kashmir Shaivism can be seen in contrast to Shankara's Advaita. Advaita Vedanta holds that Brahman is inactive (niṣkriya) and the phenomenal world is an illusion (māyā). In Kashmir Shavisim, all things are a manifestation of the Universal Consciousness, Chit or Brahman. Kashmir Shavisim sees the phenomenal world (Śakti) as real: it exists, and has its being in Consciousness (Chit).
Kashmir Shaivism was influenced by, and took over doctrines from, several orthodox and heterodox Indian religious and philosophical traditions. These include Vedanta, Samkhya, Patanjali Yoga and Nyayas, and various Buddhist schools, including Yogacara and Madhyamika, but also Tantra and the Nath-tradition.
Contemporary vernacular Advaita
Advaita is also part of other Indian traditions, which are less strongly, or not all, organised in monastic and institutional organisations. Although often called "Advaita Vedanta," these traditions have their origins in vernacular movements and "householder" traditions, and have close ties to the Nath, Nayanars and Sant Mat traditions.
Ramana Maharshi (30 December 1879 – 14 April 1950) is widely acknowledged as one of the outstanding Indian gurus of modern times. Ramana's teachings are often interpreted as Advaita Vedanta, though Ramana Maharshi never "received diksha (initiation) from any recognised authority".[web 9] Ramana himself did not call his insights advaita:
D. Does Sri Bhagavan advocate advaita?
Natha Sampradaya and Inchegeri Sampradaya
The Natha Sampradaya, with Nath yogis such as Gorakhnath, introduced Sahaja, the concept of a spontaneous spirituality. Sahaja means "spontaneous, natural, simple, or easy".[web 12] According to Ken Wilber, this state reflects nonduality.
Nonduality as common essence
This nondual consciousness is seen as a common stratum and of the same essence in different spiritual traditions. According to Renard, these are based on an experience or intuition of "the Real".
Nondualism as common essence prefers the term "nondualism", instead of monism, because this understanding is "nonconceptual", "not graspapable in an idea".[note 21] Even to call this "ground of reality", "One", or "Oneness" is attributing a characteristic to that ground of reality. The only thing that can be said is that it is "not two" or "non-dual":[web 13] According to Renard, Alan Watts has been one of the main contributors to the popularisation of the non-monistic understanding of "nondualism".[note 22]
Nondualism and "religious experience"
Personal religious or mystical experience, especially "enlightenment" or the realization of the illusory nature of the autonomous "I" or self, is a key element in modern western nondual thought. It is the personal realization that ultimate reality is nondual, and is thought to be a validating means of knowledge of this nondual reality.
The notion of "religious experience" can be traced back to William James, who used the term "religious experience" in his book, The Varieties of Religious Experience. The origins of the use of this term can be dated further back.
In the 18th, 19th, and 20th centuries, several historical figures put forth very influential views that religion and its beliefs can be grounded in experience itself. While Kant held that moral experience justified religious beliefs, John Wesley in addition to stressing individual moral exertion thought that the religious experiences in the Methodist movement (paralleling the Romantic Movement) were foundational to religious commitment as a way of life.
Wayne Proudfoot traces the roots of the notion of "religious experience" to the German theologian Friedrich Schleiermacher (1768–1834), who argued that religion is based on a feeling of the infinite. The notion of "religious experience" was used by Schleiermacher and Albert Ritschl to defend religion against the growing scientific and secular critique, and defend the view that human (moral and religious) experience justifies religious beliefs.
Such religious empiricism would be later seen as highly problematic and was – during the period in-between world wars – famously rejected by Karl Barth. In the 20th century, religious as well as moral experience as justification for religious beliefs still holds sway. Some influential modern scholars holding this liberal theological view are Charles Raven and the Oxford physicist/theologian Charles Coulson.
Development of the modern understanding of "nondualism"
The idea of nonduality as "the central essence" is a universalistic and perennialist idea, which is part of a modern mutual exchange and synthesis of ideas between western spiritual and esoteric traditions and Asian religious revival and reform movements.[note 24] Western predecessors are, among others, Swedenborgianism, Unitarianism, Orientalism, Transcendentalism, Theosophy, the idea of a Perennial Philosophy, New Age, and Wilber's synthesis of western psychology and Asian spirituality.
The western world has been exposed to Indian religions since the late 18th century. The first western translation of a Sanskrit text was made in 1785. It marked a growing interest in Indian culture and languages. The first translation of the dualism and nondualism discussing Upanishads appeared in two parts in 1801 and 1802 and influenced Arthur Schopenhauer, who called them "the consolation of my life". Early translations also appeared in other European languages.
Transcendentalism and Unitarian Universalism
Transcendentalism was an early 19th-century liberal Protestant movement that developed in the 1830s and 1840s in the Eastern region of the United States. It was rooted in English and German Romanticism, the Biblical criticism of Herder and Schleiermacher, and the skepticism of Hume.[web 14]
The Transcendentalists emphasised an intuitive, experiential approach of religion.[web 15] Following Schleiermacher, an individual's intuition of truth was taken as the criterion for truth.[web 15] In the late 18th and early 19th century, the first translations of Hindu texts appeared, which were read by the Transcendentalists and influenced their thinking.[web 15] The Transcendentalists also endorsed universalist and Unitarianist ideas, leading to Unitarian Universalism, the idea that there must be truth in other religions as well, since a loving God would redeem all living beings, not just Christians.[web 15][web 16]
Among the transcendentalists' core beliefs was the inherent goodness of both people and nature. Transcendentalists believed that society and its institutions—particularly organized religion and political parties—ultimately corrupted the purity of the individual. They had faith that people are at their best when truly "self-reliant" and independent. It is only from such real individuals that true community could be formed.
A major force in the mutual influence of eastern and western ideas and religiosity was the Theosophical Society. It searched for ancient wisdom in the east, spreading eastern religious ideas in the west. One of its salient features was the belief in "Masters of Wisdom",[note 26] "beings, human or once human, who have transcended the normal frontiers of knowledge, and who make their wisdom available to others". The Theosophical Society also spread western ideas in the east, aiding a modernisation of eastern traditions, and contributing to a growing nationalism in the Asian colonies.[note 27]
According to the Perennial Philosophy, there is an ultimate reality underlying the various religions. This ultimate reality can be called "Spirit" (Sri Aurobindo), "Brahman" (Shankara), "God", "Shunyata" (Emptiness), "The One" (Plotinus), "The Self" (Ramana Maharshi), "The Dao" (Lao Zi), "The Absolute" (Schelling) or simply "The Nondual" (F. H. Bradley). Ram Dass calls it the "third plane" – any phrase will be insufficient, he maintains, so any phrase will do.
This popular approach finds supports in the "common-core thesis". According to the "common-core thesis", different descriptions can mask quite similar if not identical experiences: The "common-core thesis" is criticised by "diversity theorists" such as S.T Katz and W. Proudfoot. They argue that
[N]o unmediated experience is possible, and that in the extreme, language is not simply used to interpret experience but in fact constitutes experience.
The New Age movement is a Western spiritual movement that developed in the second half of the 20th century. Its central precepts have been described as "drawing on both Eastern and Western spiritual and metaphysical traditions and infusing them with influences from self-help and motivational psychology, holistic health, parapsychology, consciousness research and quantum physics". The term New Age refers to the coming astrological Age of Aquarius.[web 17]
The New Age aims to create "a spirituality without borders or confining dogmas" that is inclusive and pluralistic. It holds to "a holistic worldview", emphasising that the Mind, Body and Spirit are interrelated and that there is a form of monism and unity throughout the universe.[web 18] It attempts to create "a worldview that includes both science and spirituality" and embraces a number of forms of mainstream science as well as other forms of science that are considered fringe.
A Course in Miracles
Gary Renard presents an interpretation of nondualism that recognises only "God" (i.e. absolute reality) as existing in any way, and nothing else existing at all. According to Gloria and Kenneth Wapnick, the influence of (Asian and western) strands of nondual thought can be found throughout modern western spirituality, such as A Course in Miracles.[note 28]
Neo-Advaita is a New Religious Movement based on a modern, western interpretation of Advaita Vedanta, especially the teachings of Ramana Maharshi. According to Arthur Versluis, neo-Advaita is part of a larger religious current which he calls immediatism,[web 19] "the assertion of immediate spiritual illumination without much if any preparatory practice within a particular religious tradition."[web 19] Neo-Advaita is criticized for this immediatism and its lack of preparatory practices.[note 29][note 30] Notable neo-advaita teachers are H. W. L. Poonja and his students Gangaji, Andrew Cohen,[note 31], and Eckhart Tolle.
New Madhyamaka Buddhism movements
An alternative understanding of nondualism is offered by some Madhyamaka-inspired writers,[web 23][web 24][web 25] stressing that there is no transcendental reality beyond this phenomenal world.[web 26][note 32]
Apart from Hinduism and Buddhism, self-proclaimed nondualists have also discerned nondulaism in other religious traditions.
Sikh theology suggests human souls and the monotheistic God are two different realities (dualism), distinguishing it from the monistic and various shades of nondualistic philosophies of other Indian religions. However, Sikh scholars have attempted to explore nondualism exegesis of Sikh scriptures, such as during the neocolonial reformist movement by Bhai Vir Singh of the Singh Sabha. According to Mandair, Singh interprets the Sikh scriptures as teaching nonduality.
Taoism's wu wei (Chinese wu, not; wei, doing) is a term with various translations[note 33] and interpretations designed to distinguish it from passivity. The concept of Yin and Yang, often mistakenly conceived of as a symbol of dualism, is actually meant to convey the notion that all apparent opposites are complementary parts of a non-dual whole.
Jewish traditions and Hasidism
Judaism has within it a strong and very ancient mystical tradition that is deeply nondualistic. "Ein Sof" or infinite nothingness is considered the ground face of all that is. God is considered beyond all proposition or preconception. The physical world is seen as emanating from the nothingness as the many faces "partsufim" of god that are all a part of the sacred nothingness.
The Cloud of Unknowing – an anonymous work of Christian mysticism written in Middle English in the latter half of the 14th century – advocates a mystic relationship with God. The text describes a spiritual union with God through the heart. The author of the text advocates centering prayer, a form of inner silence. According to the text God can not be known through knowledge or from intellection. It is only by emptying the mind of all created images and thoughts that we can arrive to experience God. According to the text God is completely unknowable by the mind. God is not known through the intellect but through intense contemplation, motivated by love, and stripped of all thought.
Christian Science has been described as nondual. In a glossary of terms written by the founder, Mary Baker Eddy, matter is defined as illusion, and when defining 'I, or Ego' as the divine in relationship with individual identity, she writes "There is but one I, or Us, but one divine Principle, or Mind, governing all existence" – continuing – ". . .whatever reflects not this one Mind, is false and erroneous, even the belief that life, substance, and intelligence are both mental and material."
According to the teachings of The Infinite Way, God is a non-dual experience. Joel Goldsmith wrote that thought and ideas in the mind take people away from the realization of God. To experience God, he recommended meditation and for the subject to tune into the present moment so duality of the subject disappears.
Thomism, though not non-dual in the ordinary sense, considers the unity of God so absolute that even the duality of subject and predicate, to describe him, can be true only by analogy. In Thomist thought, even the Tetragrammaton is only an approximate name, since "I am" involves a predicate whose own essence is its subject.
Since its beginning, Gnosticism has been characterized by many dualisms and dualities, including the doctrine of a separate God and Manichaean (good/evil) dualism. Ronald Miller interprets the Gospel of Thomas as a teaching of "nondualistic consciousness".
The precepts of Neoplatonism of Plotinus (2nd century) assert nondualism, Some scholars suggest a possible link of more ancient Indian philosophies on Neoplatonism, while other scholars consider these claims as unjustified and extravagant with the counter hypothesis that nondualism developed independently in ancient India and Greece.
The nondualism of Advaita Vedanta and Neoplatonism have been compared by various scholars, such as J. F. Staal, Frederick Copleston, Aldo Magris and Mario Piantelli, Sarvepalli Radhakrishnan, Gwen Griffith-Dickson, John Y. Fenton and Dale Riepe.
The notion of "experience" has been criticised. Robert Sharf points out that "experience" is a typical Western term, which has found its way into Asian religiosity via western influences.[note 34]
Insight is not the "experience" of some transcendental reality, but is a cognitive event, the (intuitive) understanding or "grasping" of some specific understanding of reality, as in kensho or anubhava.
"Pure experience" does not exist; all experience is mediated by intellectual and cognitive activity. A pure consciousness without concepts, reached by "cleaning the doors of perception",[note 35] would be an overwhelming chaos of sensory input without coherence.
The idea of a common essence has been questioned by Yandell, who discerns various "religious experiences" and their corresponding doctrinal settings, which differ in structure and phenomenological content, and in the "evidential value" they present. Yandell discerns five sorts:
- Numinous experiences – Monotheism (Jewish, Christian, Vedantic)
- Nirvanic experiences – Buddhism, "according to which one sees that the self is but a bundle of fleeting states"
- Kevala experiences – Jainism, "according to which one sees the self as an indestructible subject of experience"
- Moksha experiences – Hinduism, Brahman "either as a cosmic person, or, quite differently, as qualityless"
- Nature mystical experience
The specific teachings and practices of a specific tradition may determine what "experience" someone has, which means that this "experience" is not the proof of the teaching, but a result of the teaching. The notion of what exactly constitutes "liberating insight" varies between the various traditions, and even within the traditions. Bronkhorst for example notices that the conception of what exactly "liberating insight" is in Buddhism was developed over time. Whereas originally it may not have been specified, later on the Four Truths served as such, to be superseded by pratityasamutpada, and still later, in the Hinayana schools, by the doctrine of the non-existence of a substantial self or person. And Schmithausen notices that still other descriptions of this "liberating insight" exist in the Buddhist canon.

- Edward Roer translates the early medieval era Brihadaranyakopnisad-bhasya as, "(...) Lokayatikas and Bauddhas who assert that the soul does not exist. There are four sects among the followers of Buddha: 1. Madhyamicas who maintain all is void; 2. Yogacharas, who assert except sensation and intelligence all else is void; 3. Sautranticas, who affirm actual existence of external objects no less than of internal sensations; 4. Vaibhashikas, who agree with later (Sautranticas) except that they contend for immediate apprehension of exterior objects through images or forms represented to the intellect."
- Kalupahana: "Two aspects of the Buddha's teachings, the philosophical and the practical, which are mutually dependent, are clearly enunciated in two discourses, the Kaccaayanagotta-sutta and the Dhammacakkappavattana-sutta, both of which are held in high esteem by almost all schools of Buddhism in spite of their sectarian rivalries. The Kaccaayanagotta-sutta, quoted by almost all the major schools of Buddhism, deals with the philosophical "middle path", placed against the backdrop of two absolutistic theories in Indian philosophy, namely, permanent existence (atthitaa) propounded in the early Upanishads and nihilistic non-existence (natthitaa) suggested by the Materialists."

- According to Loy, nondualism is primarily an Eastern way of understanding: "...[the seed of nonduality] however often sown, has never found fertile soil [in the West], because it has been too antithetical to those other vigorous sprouts that have grown into modern science and technology. In the Eastern tradition [...] we encounter a different situation. There the seeds of seer-seen nonduality not only sprouted but matured into a variety (some might say a jungle) of impressive philosophical species. By no means do all these [Eastern] systems assert the nonduality of subject and object, but it is significant that three which do – Buddhism, Vedanta and Taoism – have probably been the most influential.

- James also gives descriptions of conversion experiences. The Christian model of dramatic conversions, based on the role-model of Paul's conversion, may also have served as a model for Western interpretations and expectations regarding "enlightenment", similar to Protestant influences on Theravada Buddhism, as described by Carrithers: "It rests upon the notion of the primacy of religious experiences, preferably spectacular ones, as the origin and legitimation of religious action. But this presupposition has a natural home, not in Buddhism, but in Christian and especially Protestant Christian movements which prescribe a radical conversion." See Sekida for an example of this influence of William James and Christian conversion stories, mentioning Luther and St. Paul. See also McMahan for the influence of Christian thought on Buddhism.

- Alan Jacobs: "Many firm devotees of Sri Ramana Maharshi now rightly term this western phenomenon as 'Neo-Advaita'. The term is carefully selected because 'neo' means 'a new or revived form'. And this new form is not the Classical Advaita which we understand to have been taught by both of the Great Self Realised Sages, Adi Shankara and Ramana Maharshi. It can even be termed 'pseudo' because, by presenting the teaching in a highly attenuated form, it might be described as purporting to be Advaita, but not in effect actually being so, in the fullest sense of the word. In this watering down of the essential truths in a palatable style made acceptable and attractive to the contemporary western mind, their teaching is misleading."

[b] Richard King (1995), Early Advaita Vedanta and Buddhism, State University of New York Press, ISBN 978-0-7914-2513-8, page 64, Quote: "Atman as the innermost essence or soul of man, and Brahman as the innermost essence and support of the universe. (...) Thus we can see in the Upanishads, a tendency towards a convergence of microcosm and macrocosm, culminating in the equating of atman with Brahman".
[c] Chad Meister (2010), The Oxford Handbook of Religious Diversity, Oxford University Press, ISBN 978-0-19-534013-6, page 63; Quote: "Even though Buddhism explicitly rejected the Hindu ideas of Atman (soul) and Brahman, Hinduism treats Sakyamuni Buddha as one of the ten avatars of Vishnu."
