The problem I have is that I don't really have the vocabulary for discussing aiki clearly with someone not training in it. My instructors didn't discuss it directly - it was taught indirectly, except for a few exercises which I now think most in the art learn by rote. Much of my current understanding has come from discussions with experienced folks in other aiki arts. But it'd be a nice challenge, and would improve my ability to teach it more directly to new students, should I ever get the chance to teach again.Honestly, I think it would just be fun to see all the different perspectives we could get from the different participants.
This could be by presenting material completely within the context of a particular art (for example, you demonstrating aiki principles or Kirk teaching historical sabre methods).
Or it could be by showing something from within our arts which would be more widely applicable. For example, I expect the majority of attendees would not be groundfighting specialists. So rather than me showing the fine details of how to armbar an opponent from guard, it might be more useful for me to teach a class on how to survive and get back to your feet if someone takes you down.
But there are others here with solid backgrounds in aiki arts, so perhaps teaming up with them would be the best approach. They likely have a better vocabulary for it, and I'd learn a lot.
