The Buddha taught that everything is impermanent- flowers, tables, mountains, political regimes, bodies, feelings, perceptions, mental formations, and consciousness. We cannot find anything that is permanent. Flowers decompose, but knowing this does not prevent us from loving flowers. In fact, we are able to love them more because we know how to treasure them while they are still alive. If we learn to look at a flower in a way that impermanence is revealed to us, when it dies, we will not suffer. Impermanence is more than an idea. It is a practice to help us touch reality.
