"First, there is no se-oi [taking weight on the back]. There is no pull. One does not grip tightly the lapel or sleeve. Both feet must use fully the way of no-feet and therefore do not grip the tatami. One moves under those conditions. The other may be as strong or conditioned in a sports sense as can be, that only serves to accentuate his weaknesses. Just a drop in the hips takes his center without feeling his weight, and the other does not realize that his weight is no consideration as he falls head-first to the mat. This is dangerous so a supporting hand needs to be ready."
