A travelling monk asked an old woman the road to Taizan, a popular temple 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.'
