Re: "No Mind" - What is it?
It's the state of mind you have when walking somewhere. You don't think left, right, left, right, you just walk. You can consciously think about where you are going, you can speed up and slow down, and you can avoid puddles and dog droppings, but that doesn't effect your actual walking ability.
"No mind" is utterly ordinary; there's nothing special about it. The trick is, bringing that utterly ordinary, everyday kind of mind into the stress of combat/keiko.
