In yoga practice, the chanting of OM at the beginning and the ending of yoga classes ushers the practitioners into the time and space that is about to be spent on the mat or in meditation. It unites the group. When we chant Om together, we are aligning our bodies, minds, and spirits. Aligning with one another, and aligning with the universe. Also, OM is considered to be the mother of the bija, or “seed”- that correlate to each chakra and fuel longer chants (like Om Namah Shivaya).

In Hindu traditions, the sound OM is said to contain the entire universe.
