Book excerpt: The book in front of you is one of very few ever written about White Crane Kung Fu and the only one about Shaking Crane (Zong He) style written in English. The book introduces basic concepts of internal White Crane practice. Internal power has always been shrouded in a veil of mystery, often explained through Chinese religious and esoteric practices, believes and terminology. This book separates myths from facts and explains what internal power is and how it is generated within the body. Content is strictly focused on body mechanics and doesn't go into the realm of esoteric practices or religion of any kind. Basic methods of development, transmission and releasing of internal power are explained in detail. These methods are considered the very foundation and beginners course of Zong He Quan style, on the other hand, they are universal in their training approach and goals and could be included in practice of other internal styles, especially styles from Guangdong and Fujian provinces.
