Ohm is a special mantra, it is also called "Pranava", in other words, the primordial, sacred sound, the endless vibration of the Universe, the sound of creation. Most mantras in Buddhism, Hinduism, classical yoga, and tantra start and end with Ohm. Everything that exists in the number of three can be attributed to pranava in one way or another. This can be a trinity (body, soul, spirit), time (past, present, future), as well as Hindu supreme deities (Brahma, Vishnu, Shiva). Chunk® is connected by meaning with the eternity of the Universe.
