Even though it is all this stuff is "in Aikido". When I went to the two weekend seminars the thought kept running through my head.....
"why didn't anyone wearing a hakama ever explain it so clearly as these guys wearing sweats and tee-shirts?"
it is in there, but I think we as a community have done a very poor job of codifying and communicating it.
Maybe your experiences are different than mine, and myself and a few others are the exception (I think not), but that question keeps running through my mind.
I think some people need to believe that it's complicated or that they must absolutely in all circumstances use a japanese term, I catch myself doing it occasionally. We have this bizzare term "Pure reverse irimi" which translates as "step back."
Thinking on it we have about four different terms to avoid saying "step back."
