 So just imagine as you're opening up that the ball is elastic and your hands are stuck to it and you're pulling this elastic ball bigger and bigger so you can feel two forces happening at the same time. As you're opening up the ball is trying to pull your hands together and then as you're moving them in together you feel the ball pushing back because it's a rubber ball and it's got buoyancy. It's got elastic. Expanding, pulling, pulling that chi, chi taffy. You can imagine this chi taffy and you're pulling that. And when you're contracting, same thing. You're squeezing this energy ball. Okay?
