I have never found a better book on yoga anywhere. This book is written by a great teacher who came from India. It has a comprehensive set of yoga postures, breathing excercises and meditation. The only flaw in the book is that one should study under a teacher. For those who cannot find a teacher or would rather work alone, I strongly suggest working with inner guides. A good book on this is The Inner Guide Meditation, or a similar book. A teacher is necessary, because contrary to what others may say, yoga and other spiritual excercises do work. They work for anyone who has the time and patience to do the excercises even for a short time. Results may take years to come, but they do come. But given a teacher to see the results through which can be frightening at times, this is an excellent book and I strongly recommend it.
