Omkāra(ओंकार):- ॐकाराय नमो नमः।

 ॐकाराय नमो नमः।

Aum (also Oṃ, written in Devanagari as ॐ, in Sanskrit known as praṇava
प्रणव [lit. "to sound out loudly"] or auṃkāra (also as Omkāra) ओंकार
(lit. "auṃ syllable") is a mystical or sacred syllable in the Indian
religions, i.e. Hinduism, Buddh...ism, and Jainism.Aum
... is commonly pronounced as a long or over-long nasalized close-mid back
rounded vowel, [õːː]) though there are other enunciations pronounced 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. The Māndukya
Upanishad is entirely devoted to the explanation of the syllable. The
syllable is taken to consist of three phonemes, a, u and m, variously
symbolizing the Three Vedas or the Hindu Trimurti or the three stages of
life ( birth, life and death ).The name Omkara is taken as a name of God in the Hindu revivalist Arya Samaj.
