The student Tokusan used to go to Master Ryutan in the evenings to talk and to listen. One night, it was very late before he was finished asking questions.
"Why don't you go to bed?" asked Ryutan.
Tokusan bowed, and lifted the screen to go out. "The hall is very dark," he said.
"Here, take this candle," said Ryutan, lighting one.
Tokusan took the candle.
Ryutan leaned forward, and blew it out.
