Ground connection, or rebound?

Some of you are following the activity on our social media pages- Facebook -Twitter, etc and may have seen this article published on Keith's website. It is actually a response to another video and explains the concept of ground connection as simply redirecting the incoming energy to ground, and /or back into the opponent. It is a subtle use of the basic principle of yin becoming yang. Yielding (yin) is to make a strategic controlled withdrawal to a position of stability and strength, in order to redirect, or (in this instance) 'bounce' the opponent with his own force, by feeding it back to him. In the video  for the sake of safety we only direct, rather than bounce. This is the strategic use of one particular form of 'Jin' or trained force/ energy in Tai Chi Chuan, there are many other manifestations available. follow the link to find the video if you cannot see it below.
