For starters, it’s all about sacred threes. Most faiths have trinities in their roots and Hinduism, where om was born, is no different. Experts say these syllables can represent a slew of trios, including: the heavens, earth, and the underworld; the Hindu gods Brahma, Vishnu, and Shiva (aka creator god, sustainer god, and destroyer god); and the waking, dreaming, and dreamless states — “to represent all of consciousness,” says Yoganand.
Om is also considered the mother of the bija, or “seed” mantras — short, potent sounds that correlate to each chakra and fuel longer chants (like, say, Om Namah Shivaya). Depending on who you talk to, it relates to either the third eye or the crown chakra, connecting us to the Divine.
