When virtue is lost, benevolence appears, when benevolence is lost right conduct appears, when right conduct is lost, expedience appears. Expediency is the mere shadow of right and truth; it is the beginning of disorder.
LaoziBetter stop short than fill to the brim. Oversharpen the blade, and the edge will soon blunt. Amass a store of gold and jade, and no one can protect it.
