Perhaps a better question is not who knows *about* these things or is supposedly doing these things or things like these-but rather who is displaying real skills wrought from them or things like them? Judging from hands-on and from the testimony of students who have themselves compared notes between those in Aikido who have "said" they know and can do- some right here on Aikiweb- and those who actually *can* do -there appears to be a serious difference.
At what point does chronological placement and pedagogy lead to nothing more but misleading intellectual miasma. Some may not be satisfied with an academic search, or knowing *about* them. They may be looking to gain real skills from folks who can readily make use of the knowledge outside of an abstract. I've read long descriptive details from folks who had all the pieces just right. And even longer, agonizing, mechanical descriptions from men who it turns out- didn't have a clue. Then I've met others who were disinterested in long discussions but could deliver and hands-on could show you what they were doing on the inside.
Which leads back to the five famous words…"It has to be felt."
Then, it has to be trained and worked on.
I would like to "feel" and experience what you are talking about here Mr Harden. Do you have a specific training methodology to teach these skills to newbies and develop the same real-time characteristics in them?
So, who here does train in body method skills and not just technique??
