I've had this book since 1995 and have practised on and off since then. Beryl's book is inspiring to read, she really encourages the reader to practice, and to practice it correctly, to avoid injury. She doesn't patronise the reader and keeps yoga to a level which is easier for westerners to grasp. The pictures are very good and she'll guide you through the positions, always mentioning how a beginner should approach it. I can now achieve positions with my body which I never thought possible, and physical and mental improvements are noticeable within 3 months of regular practice. Best of all, yoga can be done at home, without having to fork out for expensive gym fees! I'd recommend this book to anyone who is disciplined or wants to be! She also offers advice on how to eat more healthily and meditate. When practiced correctly, sweat will be pouring from your body and you will feel pretty tired by the end of the practice. Power Yoga is NOT for the faint hearted!
