"A monk asked Ts'ui-wei about the meaning of Buddhism. Ts'ui-wei answered: "Wait until there is no one around, and I will tell you." Some time later the monk approached Ts'ui-wei again, saying, "There is nobody here now. Please answer me." Ts'ui-wei led him out into the garden ad went over to the bamboo grove, saying nothing. Still the monk did not understand, so at last Ts'ui-wei said, "Here is a tall bamboo; there is a short one!""
