Om is a sacred syllable representing Brahman. By itself Brahman is incomprehensible; so a symbol becomes mandatory to help us realize the Unknowable. For those who believe Om symbolizes the most profound concepts.
What I find to be most compelling and beautiful about the Om is it's not a word but rather an intonation, which, like music, transcends the barriers of age, race, culture and even species.
A lesson we should all subscribe to. As many Yogis do.
Perfect for any yoga enthusiast from beginning to advanced.
