Āstika (Sanskrit: आस्तिक), literally means "there is, there exists".[1] Nāstika (नास्तिक) literally means "not āstika". These words are also concepts used to classify and contrast Indian philosophies. Āstika has been defined in one of three ways; as those who accept the epistemic authority of Vedic literature, as those who accept that Atman (Soul, Self) exists, or as those who accept that Ishvara (God) exists.[2][3] In contrast, nāstika are those who deny the respective foundational definitions of āstika.[2] The various definitions for āstika and nastika philosophies has been disputed since ancient times, and there is no consensus.[2][4] Buddhism is considered to be nāstika, but the Gautama Buddha is considered an avatar of Vishnu in some Hindu traditions.

The most studied Āstika schools of Indian philosophies, sometimes referred to as orthodox schools, are six: Nyāyá, Vaiśeṣika, Sāṃkhya, Yoga, Mīmāṃsā, and Vedānta – all schools of Hinduism. The most studied Nāstika schools of Indian philosophies, sometimes referred to as heterodox schools, are four: Buddhism, Jainism, Cārvāka and Ājīvika – last two are also schools of Hinduism.[5][6] This orthodox-heterodox terminology is a construct of Western languages, and lacks scholarly roots in Sanskrit. Recent scholarly studies[2] state that there have been various heresiological translations of Āstika and Nāstika in 20th century literature on Indian philosophies, but quite many are unsophisticated and flawed.

Astika and Nastika do not mean "theism" and "atheism" respectively in ancient or medieval era Sanskrit literature.[2] In current Indian languages like Hindi, āstika usually means "theist", while nāstika means "atheist".[7] However, the terms are used differently in Hindu philosophy.[8] For example, Sāṃkhya is both an atheist and āstika (Vedic) philosophy.[9]


Āstika is a Sanskrit adjective (and noun) that is derived from asti ("there is or exists").[1] meaning "knowing that which exists" or "pious";[10] Nāstika (na (not) + āstika) is its negative.

As used in Hindu philosophy the differentiation between āstika and nāstika does not refer to theism or atheism.[2] The terms often, but not always, relate to accepting Vedic literature as an authority, particularly on their teachings on Self (Soul). The Veda and Hinduism do not subscribe to or include the concept of an almighty that is separate from oneself i.e. there is no concept of 'god' as in the Christian or Islamic sense. As N. N. Bhattacharyya writes:

The followers of Tantra were often branded as Nāstika by the political proponents of the Vedic tradition. The term Nāstika does not denote an atheist since the Veda presents a godless system with no singular almighty being or multiple almighty beings. It is applied only to those who do not believe in the Vedas. The Sāṃkhyas and Mīmāṃsakas do not believe in God, but they believe in the Vedas and hence they are not Nāstikas. The Buddhists, Jains, and Cārvākas do not believe in the Vedas; hence they are Nāstikas.

—N. N. Bhattacharyya[11]

Astika is also a name, such as of a Vedic scholar born to goddess Manasa (mind) and sage Jaratkaru.[12]


Manusmriti, in verse 2.11, defines Nastika as those who revile "Vedic literature based on two roots of science of reasoning (Śruti and Smriti)".[2] The 9th century Indian scholar Medhatithi analyzed this definition and stated that Nastika does not mean someone who says "Vedic literature are untrue", but rather one who says "Vedic literature are immoral". Medhatithi further noted verse 8.309 of Manusmriti, to provide another aspect of the definition of Nastika as one who believes, "there is no other world, there is no purpose in giving charity, there is no purpose in rituals and the teachings in the Vedic literature."[2]

Manusmriti does not define, or imply a definition for Astika. It is also silent or contradictory on specific rituals such as animal sacrifices, asserting Ahimsa (non-violence, non-injury) is dharma in its verses such as verse 10.63 based on Upanishadic layer of Vedic literature, even though the older layer of Vedic literature mention such sacrifices unlike the later layer of Vedic literature.[13] Indian scholars, such as those from Samkhya, Yoga, Nyaya and Vedanta schools, accepted Astika to be those that include Śabda (शब्द, Aptavacana, testimony of Vedic literature and reliable experts) as a reliable means of epistemology, but they accepted the later ancient layer of the Vedic literature to be superseding the earlier ancient layer.[2]

Definition without reference to Vedas

In contrast to Manusmiriti, the 6th century CE Jain scholar and doxographer Haribhadra, provided a different perspective in his writings on Astika and Nastika. Haribhadra did not consider "reverence for Vedas" as a marker for an Astika. He and other 1st millennium CE Jaina scholars defined Astika as one who "affirms there exists another world, transmigration exists, virtue (punya) exists, vice (paap) exists".[2][4]

The 7th century scholars Jayaditya and Vamana, in Kasikavrtti of Panini tradition, were silent on the role of or authority of Vedic literature in defining Astika and Nastika. They state, "Astika is the one who believes there exists another world. The opposite of him is the Nastika."[2][14]

Similarly the widely studied 2nd-3rd century CE Buddhist philosopher Nagarjuna, in Chapter 1 verses 60-61 of Ratnāvalī, wrote Vaiśeṣika and Sāṃkhya schools of Hinduism were Nastika, along with Jainism, his own school of Buddhism and Pudgalavadins (Vātsīputrīya) school of Buddhism.[15][16]

Definition based on belief in Atman

Astika, in some texts, is defined as those who believe in the existence of Atman (Soul, Self, Spirit), while Nastika being those who deny there is any "soul, self" in human beings and other living beings.[3][17] All six schools of Hinduism classified as Astika philosophies hold the premise, "Atman exists". Buddhism, in contrast, holds the premise, "Atman does not exist".[18][19] Anne Blackburn and Jeffrey Samuels translate Astika as "positivism" and Nastika as "negativism", with Astika illustrated by Brahmanic traditions who accepted "soul and Ishvara (God) exists", while Nastika as those traditions, such as Buddhism, who denied "soul and Ishvara exists".[20]

Classification of schools[edit]


Several Indian intellectual traditions were codified during the medieval period into a standard list of six orthodox systems or ṣaḍdarśanas (also spelled Sad Darshan), all of which cite Vedic authority as their source.[21] Nyaya, Vaisheshika, Samkhya, Yoga, Mimāṃsā and Vedanta are classified as āstika schools:

  1. Nyāyá, the school of logic
  2. Vaiśeṣika, the atomist school
  3. Sāṃkhya, the enumeration school
  4. Yoga, the school of Patañjali (which assumes the metaphysics of Sāṃkhya)
  5. Mimāṃsā, the tradition of Vedic exegesis
  6. Vedanta or Uttara Mimāṃsā, the Upaniṣadic tradition.

These are often coupled into three groups for both historical and conceptual reasons: Nyāyá-Vaiśeṣika, Sāṃkhya-Yoga, and Mimāṃsā-Vedanta.


The main schools of Indian philosophy that do not base their beliefs on the Vedas were regarded as heterodox by Brahmins:

  1. Buddhism
  2. Jainism
  3. Cārvāka
  4. Ājīvika

The use of the term nāstika to describe Buddhism and Jainism in India is explained by Gavin Flood as follows:

At an early period, during the formation of the Upaniṣads and the rise of Buddhism and Jainism, we must envisage a common heritage of meditation and mental discipline practiced by renouncers with varying affiliations to non-orthodox (Veda-rejecting) and orthodox (Veda-accepting) traditions.... These schools [such as Buddhism and Jainism] are understandably regarded as heterodox (nāstika) by orthodox (āstika) Brahmanism.


Tantric traditions in Hinduism have both āstika and nāstika lines; as Banerji writes in "Tantra in Bengal":

Tantras are ... also divided as āstika or Vedic and nāstika or non-Vedic. In accordance with the predominance of the deity the āstika works are again divided as Śākta, Śaiva, Saura, Gāṇapatya and Vaiṣṇava.


Jain usage[edit]

Jains themselves have been branded nāstika or not accepting the Vedas, and they in turn have accused many non-Jains of being nāstika. According to Jainism, nastikavada is a system of beliefs that are nāstika in nature. Jains assign the term nastika to one who is ignorant of the meaning of the religious texts[24] or those who deny the existence of the soul.[25]

The Jains acharyas, Manibhadra and Haribhadra associated Jainism of astika classification and associated the Lokayata (Charvaka) philosophy and Vedanta with nastika.[26]

Buddhist usage[edit]

Although Buddhists have been branded by orthodox or mainstream Hinduism as Nastika, the Buddhists themselves have branded only the Cārvākas as nastika. For example Nagarjuna wrote in his Ratnavali,[27] that nastikya (nihilism) leads to hell while astikya (affirmation) leads to heaven. Further, the Madhyamika philosopher Chandrakirti, who was accused of being a nastik, wrote in his Prasannapada that emptiness is a method of affirming neither being nor non-being and that nihilists are actually naive realists because they assume that things of this world have self-existent natures,[28] whereas Madhyamikas view all things as arising dependently within the context of casual conditions.

There were also Buddhists that were accused of believing in ideas outside of the Buddha's teachings, and they were called nastika in the "Bodhisattvabhumi" (a section of the Yogacarabhumi by Asanga) and the scripture also declared they should be subject to isolation so their views do not infect the rest of the Buddhist community.[29] Like the Manusmriti, the Bodhisattvabhumi also criticizes the nastika for reliance on logic only.[29]

Bhavaviveka declares that Buddhists are not nastika by refuting the nihilists annihilation of 'karmaphalasambandha' and demonstrating the transmigration of sentient beings.[30]

According to the Sallekha Sutta, belief leading to evil conduct is of three kinds, and natthika ditthi (nastikavada or nihilism), is one of them (the others being ahetuka ditthi or accidentalism and akiriya ditthi or the view of inaction).[31]

According to Buddhist texts, Astikavada is also known as Sabbathikavada.
