"[N]ot only does the fingertip have a spiral, but [there is] the spiral at the tip of your heart. Perhaps the tip of your heart is your apical fingertip. ...The ventricle, which is the beating part of the heart, has a spiral... it goes from inside-out, and outside-in. That spiral is very typical. It goes down to the apex of the heart, the tip of the heart, which is a vortex. The thing that really makes the heart a part of an active way of living."
