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