The San Szu "Advanced Mechanics and Internal Power Application" text is complete. Though the title may seem intimidating for the beginner and intermediate level martial artist, the issues covered are essential for all serious practitioners of Chinese Martial Arts and the Internal Arts or "Nei Jia" in particular. Much of the booklet deals with issues such as what is internal power, and what are simply the mechanics employed in different types of martial arts. The Internal Arts are largely demystified and their mechanics are explained in a very down to Earth manner. Thus, for any who are learning (or continue to study), these Internal Martial Arts, what is taught within this booklet is essential; as demystification will only lend itself to the acceleration of learning and thus progress. After discussing what amounts to the sophisticated mechanics employed by the Nei Jia, the reality of internal power will be discussed. Additionally, the reader will be given training methods and tips for building and applying REAL internal power - that although it is complimented by specific manners of alignment and the like - is not an issue of posture or alignment, but of the cultivation of Chi (Qi) and the ability to apply it in martial applications.
