Tai chi secrets of the Yang style : Chinese classics, translations, commentary

Summary/Review: "Since ancient times Tai Chi Chuan has been practiced as a holistic mind/body fitness system, bringing immense benefits for practitioners in health, longevity, relaxation, and concentration. But it was also practiced as an effective and deadly martial art. Because of this, the masters rarely disclosed their secrets, guarding them as closely as they would military secrets. They preserved their profound insights in obscure songs, poems, and classics, revealing only to those they considered trustworthy and ready for such knowledge."--Page [4] of cover.
