This book could only exist in audio form, and it is absolutely amazing and worth every penny. The CD's are really an instructional course in Indian music, yoga as sound, and how to use singing to heal yourself. The portions detailing Indian music, and the emotions behind this style of music, are fascinating. The CD's first introduce the author's philosophy, and encourage vocal exercises. Don't be afraid if you can't sing, it isn't really about vocal talent at all and the author will put you at ease no matter what your vocal comfort level. You then learn how the sounds of a scale relate to the body's chakras. One CD is devoted to chanting, and if you do yoga you must listen to her explanations of OM. Much of the course feels like a lesson in how to use sound in yoga, although she doesn't make a direct reference to yoga very often. My favorite of the CDs is a singing lesson on various major and minor scales, and their corresponding emotions. This CD is SO POWERFUL. You will feel yourself transform and release while you sing these amazing scales. The author has such a beautiful voice that she will move you to tears. There is even an instructional DVD. There is so much included in this audiobook that you will not be disappointed. This course is truly unique, yet will remind you of other powerful healing modalities.
