Parable: True prosperity

A rich man asked Senga to write something to the prosperity of his family continued from generation to generation.
Sengai took a large sheet of paper and wrote:
"The father died, the son died, the grandson is dead."
The rich man was angry:
- I asked you to write something for the happiness of my family. Why are you joking?
- I'm not going to joke, explained Sengai.
If your son dies before you, you is greatly disappoint you.
If your grandson dies before the son, it will break your heart.
If in your family from generation to generation will die in the order in which I wrote, that would be the natural course of life.
I call that true prosperity.
