Aum (also Om, ) is the most sacred syllable in Hinduism, symbolizing the infinite Brahman and the entire Universe. This syllable is sometimes called the "Udgitha" or "pranava mantra" (primordial mantra), because it is considered to be the primal sound, and because most mantras begin with it. It first came to light in the Vedic Tradition. As a seed syllable (bija), it is also considered holy in Esoteric Buddhism.
The Aum symbol is a ligature of Devanagari ?+? (o?, encoded in Unicode at U+0950 ?, the Tibetan script variant ? at U+0F00).
