I was also very skeptical of the tone and Shaolin exile claims that the "Grandmaster Text" has / makes. But, its underlying message is good and it is a good introduction, if not a bit childish. I wish there was more literature in the martial arts scenes. The Tao of Bioenergetics, as I isaid, is definately an original work. I know there is one professor at my university who does research on Buddhism and Cognitive science as well as the psychology of wisdom, which really is the theory behind martial arts as a life path.
