It is very refreshing to see a westerner who really understands the heart,soul,and original pupose of all yogas. Most westerners assume Yoga to be a merely stretches and postures. In reality, there are many different paths of yoga--all invented to ultimately lead the soul to complete liberation, although a lot of people (even some self-designated "gurus") don't know or lose sight of this. I was very sceptical as to whether a westerner giving an honorable representation of this majestic science, and to give an honorable IN-DEPTH presentation at that!
As Ken Wilber states (in other words) in the foreword...we DO have in Feuerstein the perfect and necessary blend of a scientifically minded scholar and devoted practitioner.
HUGE BOOK!!! The size of an actual encyclopedia. But, if you have any clue as to how deep and rich the yoga tradition is, and if you also appreciate it's beauty...or even if you think it's a bunch of hooey and want to know whether you are right or not, it is an immensely scholarly--yet readable sourcebook. MUST HAVE!
