Practice is very formal when danger is close and thus much is gone in the haze of getting good at a drill instead of learning about yourself and learning to accept what is.
Have a partner hold a covered knife and have him move in a continuous oval cutting motion that includes the space you are taking.
Start by keeping your hands to yourself and moving your body out of the way and toward his back. Keep both legs under you at all times.
Continue by letting your arms move from the movement of your body and staying close to the partner knife hand or hands.
Now add a traveling hand with the always moving knife hand. Be as light as a butterfly after a fast and never try to control the situation.
Your breath moves you, Your eyes control your boundries, Your movement shows all including you what you are afraid to accept. Let go of controlling the situation and ride the wave.
