Qi

Qi is the Chinese word for life energy, also spelled chi or ki. It is the essence used in acupuncture, qigong and taiji, as well as many other traditional arts in China and Japan. Its western counterpart is the spirit, or inspiration. This book explains how qi works, and presents several very easy exercises by which you can cultivate and increase it within yourself. It is not difficult at all, and the result will invigorate you beyond your expectations. So, give it a try.
