Gasan was sitting at the bedside of Tekisui three days before his teacher's passing. Tekisui had already chosen him as his successor. A temple recently had burned and Gasan was busy rebuilding the structure. Tekisui asked him: "What are you going to do when you get the temple rebuilt?" "When your sickness is over we want you to speak there," said Gasan. "Suppose I do not live until then?" "Then we will get someone else," replied Gasan. "Suppose you cannot find anyone?" continued Tekisui. Gasan answered loudly: "Don't ask such foolish questions. Just go to sleep."
