This is a great book!Why,you ask,is it out of print?This book reflects a time when Yoga was beginning to be widely accepted in the west from the east and so there is a slight cultural exotica flavour, which, while charming, is dated.The book is by a doctor however, and takes a clinical western approach to total health:as such I find it to be a current asset to both my medical library section and my psychology section.I can't say that for many books in my library for 30 years. Many exercises are easy and invigoating at a deep level; a few of the exercises outlined here are for master level training,they take a lot of discipline to get through the first few times and a coach would be good to have,thats how I felt.Having said that,the breathing exercise set generally and the chapter on relaxation specifically is worth the price of the book.Tons of used copies everywhere.ENJOY
