5. Nature is Uncaring

Heaven and Earth are ruthless;
To them the Ten Thousand things are but as straw dogs.
The Sage too is ruthless;
To him the people are but as straw dogs.
Yet Heaven and Earth and all that lies between
Is like a bellows
In that it is empty, but gives a supply that never fails.
Work it, and more comes out.
Whereas the force of words is soon spent.
Far better is it to keep what is in the heart.
