There is an old Chinese text written by Wang Fu-chih that neatly summarizes the Shen-Chi-Jing principles of Taoist alchemy, only using the language of the I Ching on Law-Energy-Number: “Between Heaven and Earth there exists nothing but law and energy. The energy carries the law and the law regulates the energy. Law does not manifest itself (has no form); it is only through energy that the image is formed, and the image yields the number. If this law becomes blurred the image is not right and the number is not clear. This reveals itself in great things and expresses itself in small things. Thus only a man of the highest integrity can understand this law; basing himself on its revelation he can grasp the symbols, and observing its small expressions, he can understand the auguries.”
