This book is essentially a reference text book on Yoga. In that regard, it is totally comprehensive and complete. However, I bought it on a recommendation from an acquaintance who said it was a great book to get started with yoga. It is certainly NOT THAT!!! I am a beginner yoga student and if you are or similar you could hurt yourself trying many of the poses in this book. Further, the book doesn't progress from easy poses to more difficult ones but rather skips from advanced to easy back to advanced, etc. I would NOT recommend this book if you are a beginner or are looking for a simple intro to yoga. Just looking at some of the poses hurt me.
