How do I know that loving life is not a delusion? How do I know that in hating death I am not like a man who, having left home in his youth, has forgotten the way back?...someday there will be a great awakening when we know that this is all a great dream. Yet the stupid believe that they are awake, busily and brightly assuming they understand things, calling this man ruler, and that man a herdsman- how dense!
ZhuangziThose that think that wealth is the proper thing for them cannot give up their revenues; those that seek distinction cannot give up the thought of fame; those that cleave to power cannot give the handle of it to others. While they hold their grasp of those things, they are afraid of losing them. When they let them go, they are grieved and they will not look at a single example, from which they might perceive the folly of their restless pursuits - such men are under the doom of heaven.
