While singing anything is proven to benefit you, yoga’s chants give you more. They saturate your mind with Consciousness. During the chant, you are steeping in Consciousness, and after – even for quite a while afterward – you enjoy what I call the halo effect. It’s like you have a halo – light shining around your head, because your mind is full of light. If they did brainwave studies on you before, during and after the chant, would they be able to see a difference? Yes. Can you feel the difference? It’s about feeling it. Yogis have been chanting for thousands of years. They knew about the benefits because they could feel them.
