Actually the text was intended to be a jumping off point. I don't think that furitama, ten/chi no kokyu exercises can be usefully written down so as to be comprehensible unless you have already done them.
My question, directed more generally, is what of these, or things like these, are those here actually doing, or not, and why or why not ( i.e. how did you come to do them) and how do they differ from what IS described or what those here who respond may also describe, if they do?
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.
