27.79

有菴主見僧來竪火筒曰。會麼。曰不會。菴主曰。三十年用不盡底。僧却問。三十年前用箇什麼（歸宗柔代云。也要知）。

A hermitage master, seeing a monk coming, held up a fire blowpipe and said, "Do you understand?" The monk said, "I do not understand." The hermitage master said, "It has not been exhausted by thirty years of use." The monk asked back, "What did you use before thirty years ago?" (Guizong Rou spoke in his place: "I would also like to know.")
