I received this book as a birthday present in 1980. This book was written in 1977, but the content is still very much current. With all yoga books on the market I always get tempted to buy "last" ones, but I do not like I keep coming back to this Classic - is a comprehensive tutorial that covers so much. The 400+ illustrations are simple and accurate, and will certainly help to depict asanas.
As it says, 3 volumes in 1. Firstly BREATHING.There'sdetailed information on what yoga is, relaxation, yogic hygiene, diet, sexual health and of course the detailed theory and practice of breath control (pranayama) .This first volume alone takes up 160 pages. Next volume is POSTURES which explains and describes with clear line drawings over 400 postures. You can put different types of postures into your own routine (a basic and more advanced routine is outlined). The third volume is MEDITATION.It starts with the Hindu and mystical background of yoga. Chapters on Patanjali's Raja Yoga, concentration exercises including sitting for meditation, and a chapter each on mantra yoga, trancendental meditation (TM) of Mahesh Yogi, yantra yoga, Kundalini (serpent power) yoga, yoga of action (karma), yoga of devotion (bhakti), yoga of action (jnana), psychic powers (siddhis), yoga of sex (tantrism). And much more. HIGHLY RECOMMENDED, all aspects of yoga for beginner AND advanced practicioner. Anyone who wants to integrate yoga into your life will certainly benefit from this book- go ahead and get it!
