Understanding impermanence can give us confidence, peace, and joy. Impermanence does not necessarily lead to suffering. Without impermanence, life could not be. Without impermanence, your daughter could not grow up into a beautiful young lady. Without impermanence, oppressive political regimes would never change. We think impermanence makes us suffer. The Buddha gave the example of a dog that was hit by a stone and got angry at the stone. It is not impermanence that makes us suffer. What makes us suffer is wanting things to be permanent when they are not.
