When 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.
-“Actualizing the Fundamental Point” by Zen Master Dogen
We should quickly seize enlightenment while we still have the chance. In much less than a century all of us will be dead. We cannot be sure that we will be alive even tomorrow. There is no time to procrastinate. I who am giving this teaching have no guarantee that I will live out this day.
-His Holiness the Dalai Lama
