Chi is the Chinese word for the natural energy of the universe. Chi Kung is the science of the universe's energy field, which the Chinese have been studying for four thousand years. In normal use, the term Chi Kung refers to the study of the circulation of this energy in the human body. Chi Kung theory can be applied to meditation & certain types of movement to improve physical & mental health & increase longevity. Chi theory & principles, which are similar to those of Indian Yoga, are the root of traditional Chinese & Japanese medical science, especially acupuncture. Chi theory has also led to Chi Kung Massage & Chi Kung healing, as well as Japanese Shiatsu massage. Because the field of Chi Kung is so wide & its theory so profound, it is not well understood, especially in the Western world. This book will explain the historical background of various Chi Kung styles, clarify the theory & principles, & most important of all, discuss the keys to successful training. This book will give you a firm foundation in the theory of Chi Kung, & help you to understand Chi Kung publications published by YMAA or any other source. This book is a must for anyone who is interested in Chi Kung & wishes to pursue his-her studies in greater depth.Yang, Jwing-Ming is the author of 'Root of Chinese CHI Kung, Vol. 1 - Jwing-Ming Yang - Paperback' with ISBN 9780940871076 and ISBN 0940871076.
