" Liberating insight arises both from a deep and clear observation of impermanence on momentary levels and from a wise consideration of what we already know. As a way of practicing this observation, the next time you take a walk, pay attention to the movements of your body and to things you see and hear and think. Notice what happens to all these experiences as you continue on your way. What happens to them? Where are they? When we look, we see everything continually disappearing and new things arising—not only each day or each hour, but in every moment. The truth of this is so ordinary that we have mostly stopped paying attention to it. By not paying attention, we miss the every-day, every-moment opportunity to see directly, and deeply, the changing nature of our lives. We miss the opportunity to practice the “letting-go mind.” “If you let go a little, you will have a little peace. If you let go a lot, you will have a lot of peace. If you let go completely, you will have complete peace. Your struggles with the world will have come to an end.” In addition to noticing the moment-to-moment nature of change, careful reflections on three obvious and universal aspects of impermanence can also jolt us out of the complacency of our deeply rooted habits and patterns.
