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。

Heaven & earth last forever.

The reason why
heaven & earth
are able to last forever
is because they do not live for themselves.
For this reason they endure.

Therefore sages put
themselves last,
yet also first;
their self is foreign,
yet their self is preserved.

Is it because they are selfless?

For this reason their self is fulfilled.
