See shapes of movement. Round keeps moving, doesn’t want to stop. Square is the hit, putting a sharp point to the movement. Keep energy moving as much as possible. If stuck, reverse. Feel through your senses; pay attention to your body says. Understand the qualities of movement, what you are feeling in yourself and from your opponent.
Stay relaxed, go with it as much as you can. When pulled, come in (the door is opened). When pushed, go (a window of opportunity). Sometimes you reverse; that is to counter or destroy their attack. You think about what you feel. Their press becomes your roll, which could wind up into a trap/hit.
This requires staying focused in the “Now,” a very Zen-like state of awareness. Feel with your belly. Listen with your hands. The mind watches; the body does.
