Om - The Esoteric Meaning and History
‘Om’, ‘Ohm’ or ‘Aum’ is a sacred symbol that is known generally as the sound of all creation. According to the Mandukya Upanishad, "Om is the one eternal syllable of which all that exists is but the development. The past, the present, and the future are all included in this one sound, and all that exists beyond the three forms of time is also implied in it."
