Wang Shou was travelling along with written materials on his back. At a big crossroads he caught sight of Hsü Fêng. Said Hsü Fêng: "Conduct consists of actions. Actions arise from circumstance. The person who knows has no constant pattern of conduct. Books consist of sayings. Sayings arise from knowing. Therefore the knowing person does not keep written materials. Why are you travelling along with these things on your back?" At this point Wang Shou burnt his written materials and danced round the bonfire.
