Daily Life - The natural outcome


What is more unstable than human beings' acts?

What is more meaningless than human beings' desires?

What a creature in the world can get out of its native character and rationality more than human beings have done?

What a human being changes from one pole to the other, and what he loses all things which he gained through sufferings and efforts, won't take just a second.

The natural outcome is regular and certain.

However, human beings' acts are irregular and uncertain.

Therefore, the natural outcome doesn't come from human beings' acts.
