This book is really tremendous. It is a small book, but packed full of knowledge and exercises. It describes the physiology of breathing as well as a basis of the Yogi knowledge of prana and its relation to breathing. There are many physical breathing exercises as well as 'psychic' exercises for mental and spiritual development.
It is so easy to overlook the importance of breathing and I have benefited greatly so far from this book. Just like Atkinson's Hatha Yoga, it is not meant to be read once and set aside, but more of a textbook in order to help one master breathing for optimal health and wellness. Highly recommended.
