From Seishu's blog

Seishu's reply to one of his reader's comments in regard to posture struck me as very expressive.

"We do pay attention to posture when we practice.... If your posture is bad, your strength is uncoordinated and it's hard to use or communicate it well. Then you end up relying on only the strength of your arms, for example.

Other martial arts may be different, but we practice focusing awareness on the specific location "one point", the central axis. So when you do this well, when you keep relaxed and do the waza just the same way as you do when practicing the form by yourself, as if your partner weren't even there, you can do it with no resistance.

We often use the metaphor that the power we think we have is only "the tip of the iceberg", but if you use your body skillfully, you can use your whole body. That means a posture of relaxation, and then how to use your mind. From comments 3 December 2006.
