Forrest's sink the chi Stupid Jin Trick is a representation of peng jin.
You can use what I was referring to in the other thread.
Structural alignment will eventually fail given enough force. When you are using jin, it doesn't quite work that way as the other person never can exert their full potential on you because they're always off balance.
Okay, now I can get on board with this. However, we are talking about something other then 'personal body skill' here. We are talking about taking the other persons ideas, and intention into account. This is leaving the arena of body skill and becoming a human relational skill.
Things like the other person being off balance doesn't have to do with the way you are using your body anymore, and it now has to do with how you place yourself in relation to them. These are the kinds of things I
think Ueshiba was talking about. But this is not what I have been lead to believe the main interest of the "IP" community is talking about.
