An excellent book explaining chi gung and how it works - great for both beginners and veterans of the art. I have read many other books on chi gung and always recommend this one because of it's clarity and authenticity. It's hard to find a book on chi gung that really explains what it is about, instead of just presenting moves that are hard to do without a teacher. A rare gem.
What a great book. It's one of several that I go back to repeatedly and always learn more from.
Some of the exercises may seem hard at first, but stick with it and remember that this is a process that changes you incrementally rather than all at once. :)
