Two Zen teachers, Daigu and Gudo, were invited to visit a lord. Upon arriving, Gudo said to the lord: "You are wise by nature and have an inborn ability to learn Zen."
"Nonsense," said Daigu. "Why do you flatter the blockhead? He may be a lord, but he doesn't know anything of Zen."
So, instead of building a temple for Gudo, the lord built it for Daigu and studied Zen with him.
