Ruling a big kingdom is like cooking a small fish. When a man of Tao reigns over the world, demons have no spiritual powers. Not that the demons have no spiritual powers, but the spirits themselves do no harm to men. Not that the spirits do no harm to men, but the Sage himself does no harm to his people. If only the ruler and his people would refrain from harming each other, all the benefits of life would accumulate in the kingdom.
