Re: Video definitions, "Aiki" and other terms.
Thanks for your reply; please call me "David."
I think I understand what you are saying based on the distinctions you've made, not only here, but in a related thread.
I'm glad, for one, that I've gotten clear enough on what you mean that I feel I get what you're saying.
I don't know what to call it, except perhaps,"takemusu aiki," but your comments make me recall footage of O Sensei in randori (I recall in particular a stop-motion time analysis someone did that got posted on Aikido Journal).
That level of art, in any event, does seem almost magical in combining power and movement in the midst of chaos.
My guess is that using different "movement grammars," the best martial artists develop overlapping abilities on this level.
Ironic, in a way.
My sense is that what you mean by "ju" involves the sort of body skills that good grapplers tend to share. I think those skills can overlap with the skills the IP/IS adhernent would consider constituent parts of the skill sets they aim to develop.
BTW, my sincere thanks to you and Mark for posting videos.
