Find your chushin, your center line, with your hands, one to the sky, one to the earth. Extend yourself upward and downward, draw in the 2 great extremities of the world and cup them together, like a contradiction between your hands.
Connect to your center, shaking that contradiction as you shake yourself.
Polish your center, by which I mean, shake off the accumulation of crud that happens by being in the world. Connect to the light that is your core, and open up to it, recognize your center as the true heart of you.
