you ride in a boat and watch the shore, you might assume that the shore is
moving. But when you keep your eyes closely on the boat, you can see that the
boat moves. Similarly, if you examine myriad things with a confused body and
mind you might suppose that your mind and nature are permanent. When you
practice intimately and return to where you are, it will be clear that nothing
at all has unchanging self.
