If I taught mysticism, I don't think I'd have any students, maybe one or two at most. In fact, Peter made an excellent point...."but simply because it has taken on a loaded meaning which is far better described through physical terms". This is exactly how Ki testing is done, through the physical. Without that testing, I think Ki would be just that, a mystical term, and to some it still is, but each to their own.

When I meet someone else who studies Aikido, I think GREAT!! and can't wait to learn something new,...
