Re: Where Did Ueshiba Morihei's Training Go?
1. Would need a pic, can't recall exactly what you're describing.
2. I recall vids of Tohei in more recent years doing more Ueshiba like push demos. In our particular style (Ki society related off-shoot), we do them to the chest, hips, shoulders, etc, with varying degrees of force. All with the intention of allowing you to feel and ground that force and you're expected to be able to remain stable while taking more and more force as you advance.
3. I think he considered weapons a part of HIS Aikido and not exactly something that everyone needed in order to do Aikido, so he didn't really pass them on. My feeling is that they were something he used more as an extension or expression of what he was able to do rather than integral to building his ability.
4. frequency and intensity maybe? If you agree with much of what Ellis Amdur suggests in HIPS, that many of the students who got "it", did so by taking ukemi from him often, then it's likely that it's just a matter of frequency and intensity. Kind of like attending Gasshuku. It's almost impossible to improve in that week because of the intensity and amount of constant training involved. Imagine having that day in, day out, for years from the best of the best.
Of course there's also the possiblity of them learning things from him that simply haven't been passed on or things that they learned and weren't really aware that they learned it. Things they did, as a result of being around him, that they didn't see as training and didn't do once they were away from him. Maybe that's why the few who seemed to have it never seemed to get more of it once he was gone?
5. I think this is just a by-product of society these days. You don't really get challengers much anymore and I think most people are comfortable with what their Aikido is within the context of their own training. They don't feel the need to test it. Often those that do are still comfortable doing so within the dojo.
