i have seen Ikeda sensei in a ridiculous compromise positions (not the karma sutra kind. get your head out of the gutter. you people are sicked to even think of such thing! of course, now you have a different image in your head.
). yet, while in such position, he still could demonstrate C2CC and affected uke's balance.
Actually I heard someone ask him about this one evening, after a seminar. His answer was, "I just move (as in relocate) my center to my hand".
So actually he is lined up center to center still. His center is just in a different place.
Don't ask me how he does that. I'm still trying to work it out myself.
