I have discovered this to be true in my own practice after seeing (and feeling ) it with my own teacher for a number of years.
You have a gift for explaining these concepts in text George, I strive to convey these ideas to my own students where at least I have the added extra media of the kinesthetic experience.
Ushiro Kenji's new book Karate and Ki might be of interest. This is the level on which he functions and he has a lot to say about it. Quite a bit of the book was very difficult, a reflection that I am not quite "there" yet. But there's an awful lot that made sense to me and I think would be of assistance in developing a vocabulary to describe this stuff.
My good friends Josh Drachman and Marc Abrams are Aikido folks who also train with Ushiro Sensei and the did the translation into English along with one of Ushiro Sensei's Japanese students. It was very difficult as we in America do not have a good set of terminology for talking about the "energetics" of this stuff. (The Russians are much better as they have been much more open to this kind of thing and do energy work in their martial arts and healing, etc.)
