For students of Tai Chi, Pushing Hands provides an important complement to Forms and Standing Meditation [Qigong]. When performed correctly, the motion of Tai Chi reflects the opposing influences of Yin and Yang. Applying Tai Chi movements against a human opponent teaches this balance in way that can't be learned by other means. Tai Chi teaches the Push Hands combatant to use a minimum of energy, for an excess of energy can be exploited by a skillful opponent. Circular motion is used to divert attacks from the critical center of the body. The body must be relaxed--if the body is tense or stiff, the center can be influenced from any point, while if the body is relaxed, energy can easily be dissipated or diverted. Awareness and reaction often triumph over force and aggression.
