very good book Yoga, for those who want to improve their know all the asanas and yoga postures. Despite explanations and pictures inaccessible for beginners postures (asanas). The explanations do not linger on learning yoga, I think this book is indispenssable yogis who are already practicing. This book quickly evokes the essence of yoga: overheating, relaxation, pranayama, mudras, the lock abdomina, yogic cleansing, anti-stress, meditation. The postures are classified into the following chapters: standing, ground, abdominal, balance, bending, inversions.
