Joshu Investigates

 Working with the mystery of the famous koan about our favourite scoundrel - Joshu. perhaps of the greatest Zen Masters from China. 

The case is number 31 in the Gateless Gate with Mumon's comments

A traveling monk asked an old woman the road to Taishan, a popular temple on a mountain supposed to give wisdom to the one who worships there. The old woman said: "Go straight ahead." When the monk proceeded a few steps, she said to herself: "He also is a common church-goer."

Someone told this incident to Joshu, who said: "Wait until I investigate." The next day he went and asked the same question, and the old woman gave the same answer.

Joshu remarked: "I have investigated that old woman."

Mumon’s comment: The old woman understood how war is planned, but she did not know how spies sneak in behind her tent. Old Joshu played the spy's work and turned the tables on her, but he was not an able general. Both had their faults. Now I want to ask you: What was the point of Joshu's investigating the old woman?

When the question is common

The answer is also common.

When the question is sand in a bowl of boiled rice

The answer is a stick in the soft mud.
