Your hand is an homunculous, a re-presentation of your torso. Bring your hand freely to you desk, tabletop, or counter. Let it melt onto the surface experiencing its full contact. Now, let the heel of your hand correspond to your lower back, and note the connection. Let your palm correspond to your mid-back as both open. Let your fingers correspond to your head, freeing from the hand, freeing from the torso. You could spend a lifetime perfecting this.
