The Way of Energy provides a step-by-step, almost month-to-month introduction to the practice of Qigong.
Many Qigong books are too "Eastern" for Westerners to read, or are too technical/textbook like, spending many pages going over the meridians, cavities, times of day and orientation. This is required knowledge for advanced practicioners, but gets in the way and is intimidating for introductory students.
The Way of Energy starts of with a simple, straightforward standing meditation. After a brief introduction to Qigong, Part One introduces two standing positions, discusses how to start with a few minutes then work your way up to many, a good section on breathing and has an excellent section describing the sensations most people experience when starting Qigong practice (this section is worth the price of the book for most beginners).
Part Two (which the text recommends proceeding to after a few months) introduces the Eight Pieces of the Brocade Qigong exercies (called Ba Duan Jin in this text) and introduces three additional and advanced standing positions. The reader is instructed on how to integrate these two new pieces into their practice. While the Eight Pieces of Brocade positions vary slightly from other texts, their descriptions are excellent and their purpose briefly but clearly explained.
Part Three describes four advanced standing positions and imagery exercises for the practicioner to begin managing their Chi. The last part of the book describes how to integrate these disciplines into everyday life.
In summary, an excellent introductory step-by-step guide. For more technical works, I would recommend the Qigong Meditation series by Dr. Yang, Jwing Ming (Embryonic Breathing, Small Circulation and the forthcoming book on Grand Circulation).
