Recognizing the Distinction Between Jin and Li

The following is a method I have developed to teach T’ai-Chi students the difference between jin (sometimes characterized as “correct” force) and li (sometimes characterized as “awkward” force) (read about the difference):

Two students pair off in a harmonious stance. One student (A) assumes the posture “Ward Off,” and the other student (B) assumes “Push,” as shown below:

Student A determines the amount of force to exert on the B’s hands and only presents resistance to whatever force A decides to exert. A must first relax as completely as possible and then slowly build up force against B’s hands. If A uses li (muscular contraction) to exert force, B will feel a rigidity, and if A uses jin, B will feel a spring-like resistance. If A uses li, and B then suddenly lets up her resistance, A will tend to fall forward. However, if A uses jin, then if B suddenly lets up her resistance, A will be stable, but only her arm may move forward. This way, both students get to experience the difference between the two types of strength, and after swapping roles several times, the difference should be clear. Of course, if a practitioner who already can manifest jin is present, that person should work with each student in the above manner.
