Things are impermanent, thank goodness!
The world is too sloppy for permanence. Imagine holding a permanent black marker and wearing all white clothes. Oh, and you don't have a cap for the marker. What a mess!
Impermanence allows for change.
Sure, we are sad at the moment of death. But you don't want its opposite.
Time to appreciate, rejoice, enjoy.
This life is a sacred ornament.
