Judging by the description and various reviews of this book, it seems to be an awesome read. Unfortunately, many people seemed to have not applied the methods, or thrown the book away out of fear. Please share when it arrives, I would love to hear your review.
Seems like you can read bits and pieces of it on google books. Looks very interesting. From what I’ve read so far, the power comes from a knowledge and practice of utilizing both yang and yin chi energy. Compressing that energy for storage via meditation into that chakra.
