Everything that arises, whether a drop of dew or a mountain range, will eventually change and pass away. Nothing lasts. The Tibetan word for "impermanence," says Chokyi Nyima Rinpoche, implies being "perishable, fleeting, passing, like a bubble on the water. The Buddha said that when we look at a bubble in the water it looks like it is there, like it exists, but then the next moment it is gone. Everything is like that; every single moment is changing.
