The true health benefits and the foundation for martial arts application of Tai Chi can only be achieved when the practitioner incorporates "Internal Discipline". That is, using internal movements and internal power to direct and empower external movements into Tai Chi practice. This book outlines a methodology and training routine to achieve this goal. There are underlying scientific rational and logical connections between each element of the discussion. During the learning path, the practitioner will gain benefits every step of the way.Modern Tai Chi teaching has been shrouded in ethereal language as if logical thinking and scientific analysis do not apply to Tai Chi. Without a rational framework, Tai Chi practice has degenerated into multitudes of forms with no relevance to the original internt of the practice. Many of them have movements that could cause problems for the practitioner rather than improve their health. This book is a distillation of the Wu style teaching from Young Wabu (student of Wu Chien Chuan) and thirty five years of discovery through practicing and teaching by Master Stephen Hwa. It offers personal experience and insight into Master Hwa's road of discovery such as, internal energy or internal power, Large Frame Form, Compact Form, Square Form, body posture, Fajin, Qi Gong, Silk Reeling exercise, martial art applications, health benefits. In conjunction with the Classical Tai Chi DVD series, this road and its benefits is open to anyone who sets their mind to travel it.
