The symbol Aum in the Tamil script
'''Aum''' (also 'Om',
Devanagari ॐ, Chinese: 唵) is a mystical or sacred
syllable in the
Dharmic religions.
It is placed at the beginning of most
Hindu texts as a sacred exclamation to be uttered at the beginning and end of a reading of the
Vedas or previously to any prayer or
mantra. The
Mandukya Upanishad is entirely devoted to the explanation of the syllable.
Origin, name and written symbols
With preceding ''a'' or ''ā'', the ''o'' of ''om'' in
Sanskrit grammar in
sandhi (Sanskrit: संधि, "joining") does not form
vriddhi (''au'') but
guna (''o'') per
Pāṇini 6.1.95.
The
Sanskrit name for the syllable is '', from a root '' "to shout, sound, praise", verbal '' 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
Chandogya Upanishad and the
Shrauta Sutras. More rarely used terms are '' or '', and in later times '' becomes prevalent.
The Aum symbol
is a
ligature of
Devanagari + ('', encoded in
Unicode at U+0950 , the
Tibetan script variant at U+0F00, and the Chinese at U+5535 or at U+543D).
In Hinduism
The syllable ''Aum'' is first described as all-encompassing mystical entity in the
Upanishads.
Today, in all Hindu art and all over India and Nepal, 'Aum' can be seen virtually everywhere, a common sign for
Hinduism and its
philosophy and
mythology.
Upanishads and Sutra literature
The syllable is mentioned in all the
Upanishads, specially elaborated upon in the
Taittiriya,
Chandogya and
Mandukya 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.
The
Katha Upanishad has:
:"The goal, which all
Vedas declare, which all austerities aim at, and which humans desire when they live a life of continence, I will tell you briefly it is ''Aum''"
:"The one syllable ['', 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)
[1]
The
Chandogya Upanishad (1.1.1-1) states:
:''
:"The ''udgitha'' ["the chanting", that is, the syllable om] is the best of all essences, the highest, deserving the highest place, the eighth."
The
Bhagavad Gita (8.13) has:
:''Uttering the monosyllable ''Aum'', the eternal world of Brahman, One who departs leaving the body (at death), he attains the superior goal. ''
The
Yoga Sutras of Patanjali states in verse (1:27):
:"''tasya vacakah pranavah''" which translates as, ''"God's voice is Aum."''
In the following
sutra it emphasizes, "The repetition of Om should be made with an understanding of its meaning".

Puranic Hinduism
In Puranic Hinduism, ''Aum'' is the mystic name for the Hindu
Trimurti, and represents the union of the three gods, viz. ''a'' for
Brahma, ''u'' for
Vishnu and ''m'' for Mahadev which is another name of
Shiva. The three sounds also symbolise the three
Vedas (
Rigveda,
Samaveda,
Yajurveda).
According to Hindu philosophy(see
Mandukya 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 symbolizes the final part of the cycle of existence, when Vishnu 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, Aum 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.
Dvaita
Vaishnava Dvaita philosophies teach that 'Aum' is an impersonal sound representation of Vishnu/Krishna while Hari Nama is the personal sound representation. A represents
Krishna, U Srimati
Radharani and M
jivas. According to Sridhara Svami the pranava has five parts: A, U, M, the nasal bindu and the reverberation (nada). Liberated souls meditate on the Lord at the end of that reverberation. For both Hindus and Buddhists this syllable is sacred and so laden with spiritual energy that it may only be pronounced with complete concentration.
Advaita
In
Advaita philosophy it is frequently used to represent three subsumed into one, a common theme in Hinduism. It implies that our current existence is ''mithyā'' "falsehood", that in order to know the full truth we must comprehend beyond the body and intellect the true nature of infinity. Essentially, upon
moksha (
mukti,
samadhi) 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, ''Aum'' is the signifier of the ultimate truth that all is one.
Examples of Three into One:
★ Creation (
Brahma)- Preservation (
Vishnu)- Destruction (
Shiva) into
Brahman
★ Waking- Dreaming- Dreamless Sleep into
Turiya (transcendental fourth state of consciousness)
★
Rajas (activity, heat, fire) -
Tamas (dullness, ignorance, darkness) -
Sattva (purity, light, serenity/
shanti) into
Brahman
★ Body, Speech and Mind into Oneness
In proper names
When ''Aum'' is a part of a place name (for example
Omkareshwar), or is used as a man's name, it is spelled phonetically using ordinary letters of whatever Indian alphabet is used in the area. The adherents of
Arya Samaj always use the ordinary letters अ, ऊ and म to write Aum.
In Jainism

This is how the Jain om is depicted in Jain scriptures
In
Jainism, Aum is regarded to be a condensed form of reference to the five
parameshthis, by their initials ''A+A+A+U+M'' (''). The
Dravyasamgrah quotes a
Prakrit line:
:ओम एकाक्षर पञ्चपरमेष्ठिनामादिपम् तत्कथमिति चेत "अरिहंता असरीरा आयरिया तह उवज्झाया मुणियां"
:''
:"Aum" is one
syllable made from the initials of the five parameshthis. It has been said: "Arihanta, Ashiri, Acharya, Upadhyaya,
Muni" .
Thus, ओं नमः () is a short form of the
Navkar Mantra.
In Buddhism
Buddhists place om at the beginning of their ''Vidya-Sadaksari'' or mystical formulary in six syllables (viz.,
om mani padme hum) As a seed syllable (''
bija mantra''), it is also considered holy in
Esoteric Buddhism.
With
Buddhism's evolution and breaking away from Vedic/Hindu tradition, Aum and other symbology/
cosmology/philosophies are shared with the Hindu tradition. This character often appeared as "" in Buddhist scripts in
East Asia.
In Sikhism
Main articles: Ek Onkar

Stylised ''Ek Onkar''

Simple ''Ek Onkar''
Ek Onkar (also ੴ, ਇਕ ਓਅੰਕਾਰ, ''Ik Onkar'') from Sanskrit '' "one ''" per the special sandhi rule treated above, is a central symbol of the unity of God in
Sikhism, and is commonly found on
Gurdwaras.
Guru Nanak, the founder of the Sikh religion, used the word Onkar to state the concept of a monotheistic God.
This is further clarified by Guru Nanak in his composition (Guru Nanak, Guru Granth Sahib, 929).:
:''oua(n)kaar brehamaa outhapath''
:"From Ongkaar, the One Universal Creator God, Brahma was created."
stating that Onkar is that which created Brahma and therefore preceded Brahma.
Ek Onkar is the start of the Sikh
Mool Mantra - the root basis of all Sikh sacred thought, and the first phrase of the Sikh Guru embodied in scripture, the
Guru Granth Sahib. Ek Onkar is uttered at the break of dawn every morning in the prayer of
Japji Sahib signifying the unity of God's entity.
