Om is part of the iconography found in ancient and medieval era manuscripts, temples, monasteries and spiritual retreats in Hinduism, Buddhism and Jainism. The symbol has a spiritual meaning in most Indian religions, but the meaning and connotations of Om vary between the diverse schools within and across the various traditions.
In Hinduism, Om is one of the most important spiritual symbols (pratima). It refers to Atman (soul, self within) and Brahman (ultimate reality, entirety of the universe, truth, divine, supreme spirit, cosmic principles, knowledge). The syllable is often found at the beginning and the end of chapters in the Vedas, the Upanishads, and other Hindu texts. It is a sacred spiritual incantation made before and during the recitation of spiritual texts, during puja and private prayers, in ceremonies of rites of passages (sanskara) such as weddings, and sometimes during meditative and spiritual activities such as Yoga.
The syllable is also referred to as omkara (ओंकार, oṃkāra), aumkara (औंकार, auṃkāra), and pranava (प्रणव, praṇava).

The etymological origins of Om are unclear. Some scholars consider Om to have been variously held as the "cosmic sound" or "mystical syllable" in ancient India, or simply as "affirmation to something divine", or as symbolism for abstract spiritual concepts in the Upanishads. It is found in most ancient layer of the Vedic texts such as the Rig Veda, dated to be from the 2nd millennium BCE. The hymn 1.1.1 of Rig Veda Samhita, for example, opens as
ॐ अग्निमीळे पुरोहितं यज्ञस्य देवमृत्विजम् । होतारं रत्नधातमम् ॥१॥— Rigveda 1.1.1, 
The syllable means "affirmation" in the Aranyaka layer of texts in the Vedas. Aitareya Aranyaka, for example, in verse 23.6, explains Om as an acknowledgment, melodic confirmation, something that gives momentum and energy to a hymn,
Om (ॐ) is the pratigara (agreement) with a hymn. Likewise is tatha (so be it) with a song. But Om is something divine, and tatha is something human.— Aitareya Aranyaka 23.6, 
Elsewhere in the Aranyaka and the Brahmana layers of Vedic texts, the syllable is so widespread and linked to knowledge, that it stands for the "whole of Veda". The etymological foundations of Om are repeatedly discussed in the oldest layers of the Vedic texts, as well the early Upanishads. Aitareya Brahmana, in section 5.32, for example suggests that the three phonetic components of Om (pronounced AUM) correspond to the three stages of cosmic creation, and when it is read or said, it celebrates the creative powers of the universe. The Brahmana layer of Vedic texts equate Om with Bhur-bhuvah-Svah, the latter symbolizing "the whole Veda". They offer various shades of meaning to Om, such as it being "the universe beyond the sun", or that which is "mysterious and inexhaustible", or "the infinite language, the infinite knowledge", or "essence of breath, life, everything that exists", or that "with which one is liberated". The Sama Veda, the poetical Veda, orthographically maps Om to the audible, the musical truths in its numerous variations (Oum, Aum, Ovā Ovā Ovā Um, etc.) and then attempts to extract musical meters from it.
The syllable Om evolves to mean many abstract ideas in the earliest Upanishads. Max Muller and other scholars state that these philosophical texts recommend Om as a "tool for meditation", explain various meanings that the syllable may be in the mind of one meditating, ranging from "artificial and senseless" to "highest concepts such as the cause of the Universe, essence of life, Brahman, Atman, and Self-knowledge".
The syllable is also referred to as praṇava. Other used terms are akṣara (literally, letter of the alphabet, imperishable, immutable) or ekākṣara (one letter of the alphabet), and omkāra (literally, beginning, female divine energy).
Om or Aum is also written ओ३म् (o̿m [õːːm]), where ३ is pluta ("three times as long"), indicating a length of three morae (that is, the time it takes to say three syllables) — an overlong nasalised close-mid back rounded vowel, though there are other enunciations adhered to in various traditions. The word Om may share roots with the Tamil word "Ām" (Tam:ஆம், meaing: yes) meaning yes (Ām>Aum>Om).

The syllable "Om" is described with various meanings in the Vedas and different early Upanishads. The meanings include "the sacred sound, the Yes!, the Vedas, the Udgitha (song of the universe), the infinite, the all encompassing, the whole world, the truth, the ultimate reality, the finest essence, the cause of the Universe, the essence of life, the Brahman, the Atman, the vehicle of deepest knowledge, and Self-knowledge".
The chapters in Vedas, and numerous hymns, chants and benedictions therein use the syllable Om. The Gayatri mantra from the Rig Veda, for example, begins with Om. The mantra is extracted from the 10th verse of Hymn 62 in Book III of the Rig Veda. These recitations continue to be in use, and major incantations and ceremonial functions begin and end with Om.
ॐ भूर्भुवस्व: |
भर्गो देवस्य धीमहि |
धियो यो न: प्रचोदयात् ||
Om. Earth, atmosphere, heaven.
Let us think on that desirable splendour
of Savitr, the Inspirer. May he stimulate
us to insightful thoughts.
The Chandogya Upanishad is one of the oldest Upanishads of Hinduism. It opens with the recommendation that "let a man meditate on Om". It calls the syllable Om as udgitha (उद्गीथ, song, chant), and asserts that the significance of the syllable is thus: the essence of all beings is earth, the essence of earth is water, the essence of water are the plants, the essence of plants is man, the essence of man is speech, the essence of speech is the Rig Veda, the essence of the Rig Veda is the Sama Veda, and the essence of Sama Veda is the udgitha (song, Om).
Rik (ऋच्, Ṛc) is speech, states the text, and Sāman (सामन्) is breath; they are pairs, and because they have love and desire for each other, speech and breath find themselves together and mate to produce song. The highest song is Om, asserts section 1.1 of Chandogya Upanishad. It is the symbol of awe, of reverence, of threefold knowledge because Adhvaryu invokes it, the Hotr recites it, and Udgatr sings it.
The second volume of the first chapter continues its discussion of syllable Om, explaining its use as a struggle between Devas (gods) and Asuras (demons). Max Muller states that this struggle between gods and demons is considered allegorical by ancient Indian scholars, as good and evil inclinations within man, respectively. The legend in section 1.2 of Chandogya Upanishad states that gods took the Udgitha (song of Om) unto themselves, thinking, "with this [song] we shall overcome the demons". The syllable Om is thus implied as that which inspires the good inclinations within each person.
Chandogya Upanishad's exposition of syllable Om in its opening chapter combines etymological speculations, symbolism, metric structure and philosophical themes. In the second chapter of the Chandogya Upanishad, the meaning and significance of Om evolves into a philosophical discourse, such as in section 2.10 where Om is linked to the Highest Self, and section 2.23 where the text asserts Om is the essence of three forms of knowledge, Om is Brahman and "Om is all this [observed world]".
The Katha Upanishad is the legendary story of a little boy, Nachiketa – the son of sage Vajasravasa, who meets Yama – the Indian deity of death. Their conversation evolves to a discussion of the nature of man, knowledge, Atman (Soul, Self) and moksha (liberation). In section 1.2, Katha Upanishad characterizes Knowledge/Wisdom as the pursuit of good, and Ignorance/Delusion as the pursuit of pleasant, that the essence of Veda is make man liberated and free, look past what has happened and what has not happened, free from the past and the future, beyond good and evil, and one word for this essence is the word Om.
The word which all the Vedas proclaim,
That which is expressed in every Tapas (penance, austerity, meditation),
That for which they live the life of a Brahmacharin,
Understand that word in its essence: Om! that is the word.
Yes, this syllable is Brahman,
This syllable is the highest.
He who knows that syllable,
Whatever he desires, is his.
The Maitrayaniya Upanishad in sixth Prapathakas (lesson) discusses the meaning and significance of Om. The text asserts that Om represents Brahman-Atman. The three roots of the syllable, states the Maitri Upanishad, are A + U + M. The sound is the body of Soul, and it repeatedly manifests in three: as gender-endowed body - feminine, masculine, neuter; as light-endowed body - Agni, Vayu and Aditya; as deity-endowed body - Brahma, Rudra and Vishnu; as mouth-endowed body - Garhapatya, Dakshinagni and Ahavaniya; as knowledge-endowed body - Rig, Saman and Yajur; as world-endowed body - Bhūr, Bhuvaḥ and Svaḥ; as time-endowed body - Past, Present and Future; as heat-endowed body - Breath, Fire and Sun; as growth-endowed body - Food, Water and Moon; as thought-endowed body - intellect, mind and pysche. Brahman exists in two forms - the material form, and the immaterial formless. The material form is changing, unreal. The immaterial formless isn't changing, real. The immortal formless is truth, the truth is the Brahman, the Brahman is the light, the light is the Sun which is the syllable Om as the Self.
The world is Om, its light is Sun, and the Sun is also the light of the syllable Om, asserts the Upanishad. Meditating on Om, is acknowledging and meditating on the Brahman-Atman (Soul, Self).
The Mundaka Upanishad in the second Mundakam (part), suggests the means to knowing the Self and the Brahman to be meditation, self-reflection and introspection, that can be aided by the symbol Om.
That which is flaming, which is subtler than the subtle,
on which the worlds are set, and their inhabitants –
That is the indestructible Brahman.
It is life, it is speech, it is mind. That is the real. It is immortal.
It is a mark to be penetrated. Penetrate It, my friend.
Taking as a bow the great weapon of the Upanishad,
one should put upon it an arrow sharpened by meditation,
Stretching it with a thought directed to the essence of That,
Penetrate that Imperishable as the mark, my friend.
Om is the bow, the arrow is the Soul, Brahman the mark,
By the undistracted man is It to be penetrated,
One should come to be in It,
as the arrow becomes one with the mark.
The Mandukya Upanishad opens by declaring, "Om!, this syllable is this whole world". Thereafter it presents various explanations and theories on what it means and signifies. This discussion is built on a structure of "four fourths" or "fourfold", derived from A + U + M + "silence" (or without an element).
- Aum as all states of time
- In verse 1, the Upanishad states that time is threefold: the past, the present and the future, that these three are "Aum". The four fourth of time is that which transcends time, that too is "Aum" expressed.
- Aum as all states of Atman
- In verse 2, states the Upanishad, everything is Brahman, but Brahman is Atman (the Soul, Self), and that the Atman is fourfold. Johnston summarizes these four states of Self, respectively, as seeking the physical, seeking inner thought, seeking the causes and spiritual consciousness, and the fourth state is realizing oneness with the Self, the Eternal.
- Aum as all states of consciousness
- In verses 3 to 6, the Mandukya Upanishad enumerates four states of consciousness: wakeful, dream, deep sleep and the state of ekatma (being one with Self, the oneness of Self). These four are A + U + M + "without an element" respectively.
- Aum as all of knowledge
- In verses 9 to 12, the Mandukya Upanishad enumerates fourfold etymological roots of the syllable "Aum". It states that the first element of "Aum" is A, which is from Apti (obtaining, reaching) or from Adimatva (being first). The second element is U, which is from Utkarsa (exaltation) or from Ubhayatva (intermediateness). The third element is M, from Miti (erecting, constructing) or from Mi Minati, or apīti (annihilation). The fourth is without an element, without development, beyond the expanse of universe. In this way, states the Upanishad, the syllable Om is indeed the Atman (the self).
The Shvetashvatara Upanishad, in verses 1.14 to 1.16, suggests meditating with the help of syllable Om, where one's perishable body is like one fuel-stick and the syllable Om is the second fuel-stick, which with discipline and diligent rubbing of the sticks unleashes the concealed fire of thought and awareness within. Such knowledge, asserts the Upanishad, is the goal of Upanishads. The text asserts that Om is a tool of meditation empowering one to know the God within oneself, to realize one's Atman (Soul, Self).
The Bhagavad Gita, in the Epic Mahabharata, mentions the meaning and significance of Om in several verses. For example, Fowler notes that verse 9.17 of the Bhagavad Gita synthesizes the competing dualistic and monist streams of thought in Hinduism, by using "Om which is the symbol for the indescribable, impersonal Brahman".
I am the Father of this world, Mother, Ordainer, Grandfather, the Thing to be known, the Purifier, the syllable Om, Rik, Saman and also Yajus.
The significance of the sacred syllable in the Hindu traditions, is similarly highlighted in various of its verses, such as verse 17.24 where the importance of Om during prayers, charity and meditative practices is explained as follows,
तस्य वाचकः प्रणवः ॥२७॥
His word is Om.— Yogasutra 1.27, 
Johnston states this verse highlights the importance of Om in the meditative practice of Yoga, where it symbolizes three worlds in the Soul; the three times – past, present and future eternity, the three divine powers – creation, preservation and transformation in one Being; and three essences in one Spirit – immortality, omniscience and joy. It is, asserts Johnston, a symbol for the perfected Spiritual Man (his emphasis).
The medieval era texts of Hinduism, such as the Puranas adopt and expand the concept of Om in their own ways, and to their own theistic sects. According to the Vayu Purana, Om is the representation of the Hindu Trimurti, and represents the union of the three gods, viz. A for Brahma, U for Vishnu and M for Shiva. The three sounds also symbolise the three Vedas, namely (Rigveda, Samaveda, Yajurveda).
Maheshwarananda suggests that the Om reflects the cosmological beliefs in Hinduism, as the primordial sound associated with the creation of universe from nothing.
Om in scriptures of Hinduism is also called Ekam Aksharam (एकम् अक्षरम्, one syllable). Udgitha, a word found in Sama Veda and bhasya (commentaries) based on it, is synonymous therein with the syllable Om.
- ओम एकाक्षर पञ्चपरमेष्ठिनामादिपम् तत्कथमिति चेत "अरिहंता असरीरा आयरिया तह उवज्झाया मुणियां"
- Translation: Veneration to the Arhats, veneration to the perfect ones, veneration to the masters, veneration to the teachers, veneration to all the monks in the world.
- AAAUM (or just "Om") is one syllable short form of the initials of the five parameshthis: "Arihant, Ashiri, Acharya, Upajjhaya, Muni".
Esoteric Buddhists place om at the beginning of their Vidya-Sadaksari ("om mani padme hum") as well in as most other mantras and dharanis. Moreover, as a seed syllable (a bija mantra) aum is considered holy in Esoteric Buddhism.
Nio guardian kings and Komainu lion-dogs
Aum is symbolically presented with Nio (仁王 ) statues in Japan, and equivalent in East Asia. Nio are present as pairs, in front of Buddhist temple gates and stupas, in the form of two fierce looking guardian kings (Vajra). One has an open mouth, believed by Buddhists to be symbolically speaking "A"; the other has closed mouth, symbolically speaking "UM" (or, "Un" in local transliteration). The two together are traditionally believed to saying "AUM", the vajra-breath, or the Absolute in Sanskrit.
Komainu (狛犬), also called lion-dogs, found in Japan, Korea and China, also occur in pair before Buddhist temples and public spaces. One has open mouth (Agyo), the other closed (Ungyo). Like Nio statues, they are traditionally interpreted to be saying the start and end of "Aun" – a transliteration of the Sanskrit sacred syllable Aum (or Om), signifying the start and end of everything.
Ik Onkar, iconically represented as ੴ in the Sri Guru Granth Sahib (although sometimes spelt out in full as ਏਕੰਕਾਰੁ) is the statement of singularity in Sikhism, that is 'there is one God'. The phrase is a compound of the numeral one (ik) and onkar, states Doniger, canonically understood in Sikhism to refer to "absolute monotheistic unity of God". Ik Onkar has a prominent position at the head of the Mul Mantar and the opening words of the Sri Guru Granth Sahib.
The Onkar of Sikhism is related to Om – also called Omkāra – in Hinduism. Some Sikhs disagree that Ik Onkar is same as Om. Onkar is, states Wazir Singh, a "variation of Om (Aum) of the ancient Indian scriptures (with a slight change in its orthography), implying the seed-force that evolves as the universe". Ek Onkar is the "Mul Mantra" in Sikh teachings and represents "One God", explains Gulati, where "Ek" means One, and Onkar is "equivalent of the Hindu "Om" (Aum)". Guru Nanak wrote a poem entitled Oankar, which attributes the sense of speech to the Divinity, suggesting him to be the "Om-maker".
Oankar ('the Primal Sound') created Brahma, Oankar fashioned the consciousness,
From Oankar came mountains and ages, Oankar produced the Vedas,
By the grace of Oankar, people were saved through the divine word,
By the grace of Oankar, they were liberated through the teachings of the Guru.— Ramakali Dakkhani, Adi Granth 929-930, Translated by Pashaura Singh
Ik Aumkara appears at the start of Mul Mantra, states Kohli, and it occurs as "Aum" in the Upanishads and in Gurbani. However, the meaning of Oankar in the Sikh tradition, states Pashaura Singh, is quite different in certain respects than those in other Indian philosophical traditions.
The Brahmic script om-ligature has become widely recognised in western counterculture since the 1960s. As to its precise graphic form, the Vedic or Indian om is what most Westerners are used to, and the Tibetan alphabet om is less widespread in popular culture. Even Tibetan handicrafts made in India tend to use the Devanagari script om for recognisability.
Phonologically, the syllable is /aum/, which is regularly monophthongised to [õː] in Sanskrit. It is sometimes also written with pluti, as o3m (ओ३म्), notably by Arya Samaj. When occurring within a Sanskrit utterance, the syllable is subject to the normal rules of sandhi in Sanskrit grammar, however with the additional peculiarity that after preceding a or ā, the au of aum does not form vriddhi (au) but guna (o) per Pāṇini 6.1.95 (i.e. 'om').
The Om symbol, with epigraphical variations, is found in many southeast Asian countries. For example, it is called Unalom or Aum in Thailand and has been a part of various flags and official emblems such as in the Thong Chom Klao of King Rama IV. The Cambodian official seal has similarly incorporated the Aum symbol.
The Om or Aum symbol is found on ancient coins, in regional scripts. In Sri Lanka, for example, coins dated to be from the 1st to 4th century CE period, are embossed with Aum along with other symbols. The syllable is also symbolized in ancient sculpture, such as the dancing Shiva from the 10th to 12th century CE; the dance posture itself, states Joseph Campbell, represents AUM symbolizing the entirety of "consciousness, universe" and the message that God is within a person and without.
Scholars have proposed two versions of Om in Brahmi script that was in use in parts of India during the 1st millennium BCE. One theory states that Indian-styled Swastika is "a monogrammatic representation of the syllable Om, wherein two Brahmi 'O's were superposed crosswise and the 'm' was represented by dot". A commentary in Nature considers this theory questionable and unproven. The second theory states that Om was represented using the Brahmi symbols for "A", "U" and "M", and that this may have influenced the unusual epigraphical features of the symbol ॐ for Om.
