Re: Aiki and Kokyu Ryoku
What about internal power makes it not universal? When I read that doka, I see an example of him discussing what aiki is, ultimately. It does not touch on the process of getting it though. kokyu ryoku isn't aiki, but IMO it's certainly one of the things you would need to create aiki and based on your quotes it seems like he stressed that to his students. Almost as if saying doing these techniques with kokyu ryoku is what makes aiki. I recall hearing this somewhere else before too.... no kokyu, no aikido.
So if aiki needs kokyu ryoku, as your post suggests, how do you create kokyu ryoku if not internal?
