Re: Functional Ki Skills
Yes it does. I'm very glad you started posting here.
Some insight ocurred to me while reading your post. Gleason sensei often talks about how we set up initial tension and then release it while we are using our body's weight. This kind of sets up a more dynamic approach to using your middle without tension while doing waza. That is a fairly big difference in the way it seems that he does aikido and the way many others do (in that I never feel them set that initial tension up - because they are so busy blending and almost avoiding my push into their center when I grab them).
Also, if you grab my wrist, and I stay relaxed yet inflated (for lack of a better term) and keep my wrist up and fnigers down and walk in a direction that is just slightly going past your front you will be lifted up by just maintaining your grab (and having to walk backwards in the same way you suggested to maintain that grab). I'm not sure how that drill exactly fits into "weight underside" or is that extend ki?! That's the problem, I can do some of these things, but I can't map a term onto the experience so the terms say a bit meaningless to me! Sorry to add more (of my) confusion...
