Re: What's With All the Pushing?
I think I heard the pushing/pulling thing best described as the expansion and contraction of energy, not necessarily as a physical force. No two objects can occupy the same space..., right? The thought is that I do not "push" someone out of space I want to occupy, I either expand into the space or contract and draw my partner [out of the space]; in this sense, pressure is always "pushing" on my partner's center. We call it "pressure, release." Apply pressure, then release energy (think of the dynamics of air pressure in weather fronts...)
In a nutshell, I simply occupy space that is required by uke to continue attacking (forestalling the attack). The trickery is how to occupy the space without contest (either expanding into the space, or drawing uke out of the space). Dang shihans.
