天長地久。天地所以能長且久者，以其不自生，故能長生。是以聖人後其身而身先；外其身而身存。非以其無私耶？故能成其私。

The Tao of Heaven is eternal, and the earth is long enduring. Why are they long enduring?
They do not live for themselves; thus they are present for all beings.
The Master puts themselves last; And finds themselves in the place of authority.
They detach themselves from all things; Therefore they are united with all things.
They give no thought to self.
They are perfectly fulfilled.
