This book is probably the only one I've found that answers the real questions: "What is chi? Where did it come from? and, what can you do with it?" While the last section of the book illustrates some basic taichi exercises that anyone can do at home, the content would be valuable to those studying acupuncture, herbal medicine, meditation, or chi healing as well -- not just taichi students. Warning: This book looks and sounds deceptively simple, but inside are some pretty intense statements about the Tao, the nature of life and mind and the soul which aren't the usual stuff. It will definitely challenge you to expand your views on taichi and Taoism. Since I like that type of challenge, I give this five stars.
Having practiced t'ai chi for 25 years, I can say that Master Liao's book is among the most meaningful ever written on the subject of chi. This is a book that will open a true connection to your internal life force, and begin to help you develop that energy for the good of yourself, and the world. Read this book if you have any interest in developing your inner spiritual life.
