The "Om" or "Aum" symbol in Devanagari

Om (; in Devanagari as ओं oṁ [õː], औं auṃ [ə̃ũ], or ओ३म् om [õːːm]) is a mantra and mystical sound of Hindu origin (geographically India and Nepal), sacred and important in various Dharmic religions such as Hinduism, Buddhism and Jainism. The syllable is also referred to as omkara (ओंकार oṃkāra) or aumkara (औंकार auṃkāra), literally "om syllable", and in Sanskrit it is sometimes referred to as praṇava, literally "that which is sounded out loudly".

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 received traditions. It is placed at the beginning of most Hindu texts as a sacred incantation to be intoned at the beginning and end of a reading of the Vedas or prior to any prayer or mantra. It is used at the end of the invocation to the god being sacrificed to (anuvakya) as an invitation to and for the latter to partake of.

Name, phonology and written representation

The Sanskrit name for the syllable is praṇava, from a root nu "to shout, sound", verbal pra-nu- being attested as "to make a humming or droning sound" in the Brahmanas, and taking the specific meaning of "to utter the syllable om" in the Chāndogya Upanishad and the Shrauta Sutras. More rarely used terms are akṣara (lit. symbol, character) or ekākṣara (lit. one symbol, character), and in later times omkāra becomes prevalent.

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 16px (oṃ, encoded in Unicode at U+0950 ) is a ligature of Devanagari (U+0913) + (U+0901).

The syllable "om" is first described as all-encompassing mystical entity in the Upanishads. Today, in all Hindu art and all over Nepal and India, 'om' can be seen virtually everywhere, a common sign for Hinduism and its philosophy and theology. Hindus believe that as creation began, the divine, all-encompassing consciousness took the form of the first and original vibration manifesting as sound "OM".[1] Before creation began it was "Shunyākāsha", the emptiness or the void. Shunyākāsha, meaning literally "no sky", is more than nothingness, because everything then existed in a latent state of potentiality. The vibration of "OM" symbolises the manifestation of God in form ("sāguna brahman"). "OM" is the reflection of the absolute reality, it is said to be "Adi Anadi", without beginning or end and embracing all that exists.[1] The mantra "OM" is the name of God, the vibration of the Supreme. When taken letter by letter, A-U-M represents the divine energy (Shakti) united in its three elementary aspects: Bhrahma Shakti (creation), Vishnu Shakti (preservation) and Shiva Shakti (liberation, and/or destruction).[1]

Early Vedantic literature

Further information: Mandukya Upanishad

The syllable is mentioned in all the Upanishads, specially elaborated upon in the Taittiriya, Chāndogya and Māndukya Upanishad set forth as the object of profound religious meditation, the highest spiritual efficacy being attributed not only to the whole word but also to the three sounds a (a-kāra), u (u-kāra), m (ma-kāra), of which it consists. A-kara means form or shape like earth, trees, or any other object. U-kāra means formless or shapeless like water, air or fire. Ma-kāra means neither shape nor shapeless (but still exists) like the dark energy content of the Universe. Combining all three syllables produces AUM, which combines A-kāra, U-kāra, and Ma-kāra.[2] According to Yajurveda, Swastika is the symbolic representation of Om in Hinduism.

The Katha Upanishad states:

"The goal, which all Vedas declare, which all austerities aim at, and which humans desire when they live a life of conscience, I will tell you briefly it is aum"
"The one syllable [evākṣara, viz. aum] is indeed Brahman. This one syllable is the highest. Whosoever knows this one syllable obtains all that he desires.
"This is the best support; this is the highest support. Whosoever knows this support is adored in the world of Brahma." (1.2.15–17)[3]

The Chāndogya Upanishad (1.1.1-1) states:

om ity-etad akṣaram udgītham upāsīta / aum iti hy udgāyati / tasyopavyākhyānam
"The udgi:tā ["the chanting", that is, the syllable om] is the best of all essences, the highest, deserving the highest place, the eighth."

The Bhagavad Gi:tā (8.13) states that:

Uttering the monosyllable Aum, the eternal word of Brahman, one who departs leaving the body (at death), he attains the Supreme Goal (i.e., he reaches God).

In Bhagavad Gi:tā (9.17): Lord Krishna says to Arjuna – "I am the father of this universe, the mother, the support and the grandsire. I am the object of knowledge, the purifier and the syllable oṃ. I am also the Ṛig, the Sāma and the Yajur Vedas."

The Bhagvad Gi:tā (17.23) has:

om tatsatiti nirdesho brahmanstrividhah samratah
"OM, tat and sat has been declared as the triple appellation of Brahman, who is Truth, Consciousness and Bliss."

In the following sūtra it emphasises, "The repetition of Om should be made with an understanding of its meaning".[4]

Puranic Hinduism

In Purānic Hinduism, as per 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).

The Padma Purāṇa states, a-kāreṇocyate viṣṇuḥ śrīr u-kāreṇa kathyate ma-kāras tu tayor dāsaḥ pañca-viṁśaḥ prakīrtitaḥ

“[In the mantra om] the letter a signifies Lord Viṣṇu, the letter u signifies the goddess Śrī, and the letter m refers to their servant, who is the twenty-fifth element ([jīva]).” [5]

According to Hindu philosophy (see Māndukya Upanishad), the letter A represents creation, when all existence issued forth from Brahma's golden nucleus; the letter U refers to Vishnu the God of the middle who preserves this world by balancing Brahma on a lotus above himself, and the letter M symbolises the final part of the cycle of existence, when Brahma falls asleep and Shiva has to breathe in so that all existing things have to disintegrate and are reduced to their essence to him. More broadly, om is said to be the primordial sound that was present at the creation of the universe. It is said to be the original sound that contains all other sounds, all words, all languages and all mantras.

The Māndukya Upanishad is entirely devoted to the explanation of the syllable. The syllable consists of three phonemes, a (Vaishvanara),[6] u (Hiranyagarbha), and m (Ishvara), which symbolise the beginning, duration, and dissolution of the universe and the associated gods Brahma, Vishnu, and Shiva, respectively. Apart from all this, Bindu of OM represents Adi Parashakti's original nirgun form.[7]

In Advaita philosophy it is frequently used to represent three subsumed into one, a triune, a common theme in Hinduism. It implies that our current existence is mithyā and maya, "falsehood", that to know the full truth we must comprehend beyond the body and intellect the true nature of infinity. Essentially, upon moksha (mukti, samādhi) one is able not only to see or know existence for what it is, but to become it. When one gains true knowledge, there is no split between knower and known: one becomes knowledge/consciousness itself. In essence, Om is the signifier of the ultimate truth that all is one.


Depiction of Om in Jain script

In Jainism, om is considered a condensed form of reference to the Pañca-Parameṣṭhi, by their initials A+A+A+U+M (o3m). The Dravyasamgraha quotes a Prakrit line:

ओम एकाक्षर पञ्चपरमेष्ठिनामादिपम् तत्कथमिति चेत "अरिहंता असरीरा आयरिया तह उवज्झाया मुणियां"
oma ekākṣara pañca-parameṣṭhi-nāmā-dipam tatkathamiti cheta "arihatā asarīrā āyariyā taha uvajjhāyā muṇiyā"
"Om" is one syllable made from the initials of the five parameshthis. It has been said: "Arihant, Ashiri, Acharya, Upajjhaya, Muni".

Thus, ओं नमः (oṃ namaḥ) is a short form of the Navkar Mantra.


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.

In Buddhist texts of East Asian provenance, om is often written as the Chinese character (pinyin ǎn) or (pinyin wēng).

A key distinction should be made here between Buddhism as it arose in India, and Buddhism after the migration of the teachings to Tibet under the guidance of Padmasambhava. In its original form, Buddhism in India was characterised mainly by types of mindfulness meditation and did not involve the chanting of om or of mantras. The chanting of om is not mentioned even a single time in the Pali Canon (oldest known teachings attributed to The Buddha) or Visuddhimagga (ancient commentary on The Pali Canon).


Main article: Ik Onkar
Ik Onkar (One God)

Ik Onkar, iconically represented as in the Guru Granth Sahib (although sometimes spelt out in full as ਏਕੰਕਾਰੁ) is the statement of the uniqueness of God in Sikhism,[8] and is commonly translated simply as "one God".[9] Within the phrase, "ik" is the Punjabi word for "one", and "onkar" figuratively means "God" but literally means "creator of Om";[10] the suffix "-kar" derived from the verb "create", "work", or "action".[11] Thus, although "Om" is referenced, Sikhism uses it only to starkly emphasize its monotheism without subscribing to its philosophy in and of itself.[10]

Modern reception

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.[12] Even Tibetan handicrafts made in India tend to use the Devanagari script om for recognisability.
