The collection of writings that comprise the Tai Chi Classics make it a book of wisdom, rather than of tuition. One can read and reread it and re-examine the nuances of the prose each time. It is analagous to Sun Tze's art of war, but is more to do with individual combat, the application and understanding of Tai Chi Ch'uan, in terms of the integration of mind, body and spirit. It contains texts from the legendary Chang San-feng (1279 - 1368 A.D.) right up until the modern day writings of Cheng Man Ching. It has formed the literary foundation of both Yang and Wu styles of the art, and a basis for the teaching of the art. I consider it essential reading for any serious student of Tai Chi Ch'uan.
