" The Principles of Effortless Power is one of the most profound books ever written about the martial arts. It has completely changed my thinking about my own art, Aikido. Every time I read the book, it opens up entirely new areas of inquiry, possibility, and realization." -John Stone, Aikido in America "What Peter Ralston does remarkably well is to clarify what the classics have been trying to tell us, and to offer concrete direction on how to continue growing and become better in the internal arts. You can't fix Cheng Hsin on the wall with a pin, because, as you try, you realize that Cheng Hsin is the wall, and the pin, and the action, and the intent." -Frank LaManna, T'ai Chin Journal.
