TAO TE CHING V

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.
