Many pupils were studying meditation under the Zen master Sengai. One of them used to arise at nightclimb over the temple walland go to town on a pleasure jaunt.
Sengaiinspecting the dormitory quartersfound this pupil missing one night and also discovered the high stool he had used to scale the wall. Sengai removed the stool and stood there in its place.
When the wanderer returnednot knowing that Sengai was the stoolhe put his feet on the master's head and jumped down into the grounds. Discovering what he had donehe was aghast.
Sengai said: "It is very chilly in the early morning. Do be careful not to catch cold yourself."
The pupil never went out at night again.
