I've never been bothered hugely one way or another as to the precise nature of Ueshiba's internal abilities and am quite willing to accept that their one and only source was Takeda. I do still think that later methods he used for these things are of importance and worthy of study. My question would be. Did Ueshiba pass this stuff on?
Part of my point of view was that he did. Tohei got it, so why does everyone keep saying it was lost and needs reintroduction. You say that Tohei left Dan but he didn't leave the old man did he? He left his son and the aikikai so that he could teach this stuff that nobody thought was needed in the aikikai.
You misunderstand about Tohei leaving to get it. That isn't in regards to the Tohei-Kisshomaru split, it's actually about his learning from Nakamura sensei after the war. Nakamura opened Tohei's eyes to what Ueshiba was doing. So, yeah, Tohei got it from outside rather than from Ueshiba. (Course, there's Tomiki. Where did he get it from? But that's another thread)
Try reading this:
Got a lot of good stuff in there. Things like, Tohei had no idea what Ueshiba was doing, so he just copied the movements.
Another interesting part is the translation of "non-resistance". Here, the translater translates it as "non-dissension". Hmm ... throws a wrench into Erick's posts over in baseline skills.
Or this part,
"Most people assume that if someone pushes on your body, you have no choice but to move or receive it. In fact, if you are relaxed and unified it is relatively easy to redirect the incoming force into your One Point and be stable as a rock, even with several strong men trying to push you over."
