Two men walking towards one another meet in a narrow hallway, wide enough for only one to pass. "Ladies first," says one man, slyly. A riddle: What is the other man's reply? A hint: Women have not been invented.

The koan: "Just Go to Sleep"

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."

The enlightenment: Gasan has had it with this guy.
