Om (or Aum) (listenⓘ; Sanskrit: ॐ, ओम्, romanized: Oṃ, ISO 15919: Ōṁ) is a symbol representing a sacred sound, syllable, mantra, and an invocation in Hinduism.[1][2] Its written representation is one of the most important symbols of Hinduism.[3] It is variously said to be the essence of the supreme Absolute,[2] consciousness,[4][5][6] Ātman, Brahman, or the cosmic world.[7][8][9] In Indic traditions, Om serves as a sonic representation of the divine, a standard of Vedic authority and a central aspect of soteriological doctrines and practices.[10] The syllable is often found at the beginning and the end of chapters in the Vedas, the Upanishads, and other Hindu texts.[9]
