There has been much discussion about Taijiquan for health that does not include the martial aspect. I came across this form Tung Ying Chieh on that topic.
The Civil and Military Practice of Taijiquan
The civil aspect of Taijiquan is the Body (the Form). The military aspect is the Application. The civil aspect of Taijiquan may be described as a kind of calisthenics. It has the effect of promoting the jing, chi, and shen. The military aspect is based on the civil method which uses both the mind and the body. However, there are varieties in the degree of attainment. For the civil purpose it is always soft. for the military purpose it is often hard because it is used for combat. If one learns the civil aspect and ignores the military aspect, it is the body with no function. If the military aspect is not based on the civil aspect, it is a tree with no root.
Thus, as the old Chinese adage states: it is difficult to clap with one hand, also, it is impossible to support a house with a single piece of wood. Training in the civil aspect is learning about yourself. The military aspect is needed for confrontation. To fight without the foundation of the civil aspect is only foolishness. On the other hand, learning the civil aspect and ignoring the military aspect is like a man with no eyes and ears when confronted with an opponent.
