The Supreme being according to Hinduism. There is only one
God in Hinduism who is referred to as Brahma, the Hindu
god (deva)of Creation, and one of the Hindu Trinity - Trimurti. The other two Lords being Vishnu(maintainer or 'Preserver' of the universe)and Shiva(the Destroyer).
Aum(often written as Om or Ohm)found first in the Vedic scriptures of Hinduism, Aum has been seen as the first manifestation of the unmanifest Brahman (the single
Divine Ground of Hinduism) that resulted in the phenomenal universe. Essentially, all the cosmos stems from the vibration of the sound 'Aum' in Hindu cosmology.
Indeed, so sacred is it that it is prefixed and suffixed to all Hindu mantras and incantations. It is undoubtedly the most representative symbol of Hinduism.
According to Hindu
philosophy this syllable is combined of three components: the letter A, which represents creation, when all existence issued forth from Brahma's golden nucleus; the letter U, which refers to Vishnu the
god of the middle who preserves this
world by balancing Brahma on a lotus above himself. The letter U with the A, produces the sound of the
long Ō. The M produces the prolonged resonance of the nasal cavity with the mouth closed: it is the final part of the cycle of existence, when Vishnu falls asleep and Brahma has to breathe in so that all existing things have to disintegrate and are reduced to their essence to him. This is the M of Mahesha, also known as the great Lord Shiva, whose
long period of yoga begins so that the sensual
world ceases to exists.
