Update 21st February 2006
Lots of good background information across the whole field. A clear read and not pretentious.
A re-enforcement of the reasons why Yoga is good for the body and soul.
Search the second-hand bookshops for this one. Recommended as a must read. No nonsense practical yoga from every aspect. If I had to save one book from a burning library this would be it.
To keep you focussed on the nature of your life and your responsibility to care for it.
Personal change and growth are possible no matter how difficult your journey. Clearly written by a man with the experience of a life working with people who have struggled to get it together. Keep and eye out in the second-hand bookshops for this one.
