"Kirtan and chanting, which are a part of mantra yoga, are an important part of yoga education. In ancient times words and music were used to attain an altered state of mind. Music was an aid to develop the mind, spirit, emotions and sensitivity. Mantra does not mean 'word of power'. It is something you feel from deep inside, something that comes up from the depths of consciousness to the surface of your mind. Mantra is the unspoken language of the heart."
