Query: Not For Everyone.

Blah, blah, blah. It's just another exercise book. The only difference is it ties in to spiritual stuff. The main audience for this book are people who like all that chakra/astral vibration jazz. Not for people who want practical advice because the author can't seem to stay "earthbound" but has to talk about yoga culture ideas whenever possible.
