Yang Tai Chi's pushing hand exercises develop a purer and more devastating form of internal energy: chin (jing) power!
Chin is nurtured, not natural. It is hard to master because it goes from weakness to strength. In other words, chin grows only when two practitioners who are working together have unequal chin, and the weaker pushes the stronger. The hardest part of this kind of pushing hand practice comes when practitioners have to apply all the chin they possess. But after each pushing hand session, practitioners gain some chin. In the long run, one will gain a lot of chin. This is one of the reasons why it takes Tai Chi practitioners a long time to master the art and possess the chin or power.
