Big Circle to Small Circle to No Circle
The Tàijí symbol is a circle. Inside the circle there are two different energies, Yīn 陰 and Yáng 陽. One is soft and the other is hard and this is like everything in nature, like hot and cold, big and small, female and male, etc. When we make a circle, internally we are hard and externally we are soft, but once we use the circle for fighting, for example when we Fā Jìn 發勁 – Release Power, then the external will be hard and the internal will be soft, then the power comes from the inside to the outside. If we do this well, then the opponent will lose their balance, if we are using Qínná 擒拿 – Locking and controlling, then we might dislocate their joints, break their bones, or even completely finish them. So the circle movement from the body is very important. For example, someone punches at you and you block it by making contact with your forearm. Your hand is soft, but not completely soft, soft so that you can feel their arm. Because you are soft, you can circle your arm and grab their hand and even use your other hand to contact their arm. Once you twist their arm, their attack is over as you circle to control them.
