‘Baizhang said: “I want someone to go and tell something to Xitang.”
Wufeng said: “I’ll go.”
Baizhang said: “How will you speak to him?”
Wufeng said: “I’ll wait until I see Xitang, then I’ll speak.”
Baizhang said: “What will you say?”
Wufeng said: When I come back, I’ll tell you.”‘ (Zen’s Chinese Heritage)
