"From the Buddhist point of view, we human beings live in a very peculiar fashion. We view impermanent things as permanent, though everything is changing all around us. The process of change is constant and eternal. As you read these words, your body is aging. But you pay no attention to that. The book in your hand is decaying. The print is fading and the pages are becoming brittle. The walls around you are aging. The molecules within those walls are vibrating at an enormous rate, and everything is shifting, going to pieces and dissolving slowly. You pay no attention to that, either. Then one day you look around you. Your body is wrinkled and squeaky and you hurt. The book is a yellowed, useless lump; the building is caving in. So you pine for lost youth and you cry when the possessions are gone. Where does this pain come from? It comes from your own inattention. You failed to look closely at life. You failed to observe the constantly shifting flow of the world as it went by. You set up a collection of mental constructions, ‘me’, ‘the book’, ‘the building’, and you assumed that they would endure forever. They never do. But you can tune into the constantly ongoing change. You can learn to perceive your life as an ever-flowing movement, a thing of great beauty like a dance or symphony. You can learn to take joy in the perpetual passing away of all phenomena."
