Once, a large computer company, seeking to plumb the depths of the Tao, decided to psychologically test a large group of its programmers, including its Masters. Unfortunately, they did not have enough copies of the test. Luckily the test came in two separate parts, so half the group got one part, and half the second. When the group was done taking one part, the tests were exchanged, and the psychologist administering the test, following his programmed script, gave the exact same instructions that he had already given, ending with "Are there any questions?" He was about to command "Then you may begin." when one of the Masters shouted out: "Should we use the same personality as we did on the first half?" The psychologist was silent, and completely baffled. One novice in the room, and some reading this story years later, became enlightened.
