I own a LARGE number of books on "Yoga". This is one of the most worthless books I've ever read. If I had not paid for it I never would have finished reading it.
Vanda Scaravelli may have been a wonderful person but I found this/her book neither informative, inspirational nor meditative. Anything of potential value was piece meal. The most interesting page you can read for free on Amazon's "Look inside" Introduction. It does not claim to be a book on yoga and rightly so.
For a book on Yoga Read; Ray Long, Mark Stephens, Michael Stone, Sarah Powers, Bernie Clark, Donna Farhi, Gary Kraftsow, Judith Lasater, Desikachar..
