Aloha shakurav,
Chuniy used to teach Tai Chi as well. He continues to do a very active version of it, which he uses as a little more exercise during his day.
At one time he brought over a friend of his who is a very accomplished tai chi master from China. The master was a great example of slower is better, as his movement during the Moving of Yin & Yang would make one wonder if his hands were actually moving or not.
Speaking of "push hands" , Chunyi talks about how at a certain level in that training, one no longer has a center, but each cell is its own center, and then there is nothing within them for the other to sense at all.
Much Love, Shawn
