An archer competing for a clay vessel shoots effortlessly, his or her skill and concentration unimpeded. If the prize is changed to a brass ornament, the hands begin to shake. If it is changed to gold, he or she squints as if going blind. The abilities do not deteriorate, but belief in them does, as he or she allows the supposed value of an external reward to cloud the vision.
ZhuangziHow 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!
