Dao de jing
The heavens are lasting and the earth enduring.
The reason the world is able to be lasting and enduring
Is because it does not live for itself.
Thus it is able to be long-lived.
It is on this model that the sages withdraw their persons from contention
yet find themselves out in front,
Put their own persons out of mind yet find themselves taken care of.
Isn’t it simply because they are unselfish that they can satisfy their own needs?
