This is a wide-ranging introduction to the main forms of Buddhist meditation and the meditational techniques of the Chinese Ch'an masters from whose teachings Zen developed. The author has also written "Taoist Yoga" and "The Secrets of Chinese Medicine".
An interesting read, but far from practical! This is a book for people with experience and knowledge in Buddhism, intermediate or advanced level. He assumes you know the terms he is using throughout and the Buddhist concepts are not explained in an introductory way. The stories of Chinese masters are very interesting, but I would really only recommend this book to people already quite engrossed in the study/practice of (Chinese) Buddhism.
