So the bones are not being used in this kind of training? Well, I mean yes, they are holding the body up, but getting them in to alignment is not necessary?
Wouldn't this mean that the 'internal force', whatever it is, is stronger and more powerful then the bones and skeletal alignment?
No, again, see O'sensei's jo trick. That's one of the things he's demonstrating there, IMO. Heaven and earth.
I don't know that I would say that, but that's beyond my pay grade to be honest. My initial thought would be that no, it's not, but I don't think it's being stronger in a force on force sort of way. It's about how you can feel and work with forces differently compared to typical muscle usage. It has a unique feeling to it that I can't describe in words, but once you feel it I think it stands out.
