Re: Martial, spiritual, and jujutsu (split off from Funakogi Thread)
Just to quickly clarify. I don't believe That applying force where your target is weak, is ju. But rather, using the quality of ju allows me to yield to your force, which will protect me, and allow me to find a weak spot on you (if that is my goal). The force that I apply once I have found your vulnerability can come from any number of methods, but the ju is a springy quality of yielding to your force.
We are still working on our definition of Aiki, so it can include anything we agree on. I'm not sure what other "internal" people may call aiki, but I'd love to hear it.
