This is the first book I have ever met which deals equally well with the three-pronged approach to Chinese esoteric knowledge - Feng Shui, Chinese Astrology and Chinese Spiritual Alchemy ( in fact, this is a reflection of classical Jing-Qi-Shen, Body-Energy-Spirit integral method ). I strongly recommend it to any devoted practitioner of Spiritual Alchemy, especially the Spiritual Qi Gong chapters which give details about highest levels of practices such as Kan/Li, etc. And, most important, the teachings are targeted to integration of one's immortal True Self in everyday life. This is the greatest - and simplest - secret of the Golden Flower.
This book is an essential tool for the serious practitioner. It is a complete manual which provides you with clear, precise, in-deapth information no other author has yet published.
