Re: The speed of a technique
I recall a bokken class at my dojo, taught by Tres Hofmeister. He tried to tell me that my posture was poor, but I wasn't getting it. Finally, recalling that I had studied for several years at the Ki Society, he said, "Dan, weight underside." Immediately my shoulders dropped, my hips came forward and I stood up straight. "That's it," he said.
(Of course, my posture still stinks, but Tres was able to correct it for a moment, at least.)
