老子道德經(jīng)(英譯本)Lao Tze 5. Nature

Nature is not kind;
It treats all things impartially.
The Sage is not kind,
And treats all people impartially.

Nature is like a bellows,
Empty, yet never ceasing its supply.
The more it moves, the more it yields;
So the sage draws upon experience
And cannot be exhausted.
