The whole series of books by Yogani are well thought out, really well written, and simple to follow. I found this book on a specific breathing technique quite helpful. The technique is simple, which I like. All details of practice and any ways to handle odd and/or beneficial effects experienced along the way, are explained very well. There is some repetition in the series regarding the process of nervous system purification and some possibly distracting effects and how to handle them, but after reading most of these books, I simply skimmed over those sections. The books are quick to read, and approximately 100 pages each, so I could get through them in one sitting or two and then, of course, went back to check some details as necessary. The breathing technique is the key to starting this spiritual practice program. It is the basic foundational process upon which all else builds. One must learn this prior to meditating, as it assists to quiet the mind enough to start meditation. I immediately purchased these books as a gift because I liked them so much.
