The Authentic Classic of Nei Gong (Nei Gong Zhen Chuan) is an obscure text of unknown origin, yet it stands alone as the definitive text on internal energy and the generation of internal power. Hand copied and passed from teacher to student, it is one of the “secret transmissions” of Chinese martial arts.

The Authentic Classic of Nei Gong is a practical manual on internal energy development and its fundamental importance in the martial arts and fa jin (emitting force).

Divided into four parts, the text takes the reader step by step through the details of Nei Gong practice and in the final section, its application to self-defense. These four sections are:

1. Nei Gong Jing (Internal Energy Classic)
2. Na Gua Jing (Received Trigram Classic)
3. Shen Yun Jing (Transported Spirit Classic)
4. Di Long Jing (Earth Dragon Classic)

Translated by a team of experts, the text is accompanied by extensive footnotes and diagrams that clarify the more obscure passages which otherwise pre-suppose a knowledge of Daoist tests and imagery from the I-Ching (Book of Changes). The appendices further explicate the relationship of the Authentic Classic of Nei Gong to the internal martial art Xing Yi Quan.
