'When Shishuang met Daowu, he said, "What is the transcendent wisdom that meets the eye?" Daowu called to an attendant and he responded. Daowu said to him, "Add some clean water to the pitcher." After a long pause, Daowu said to Shishuang, "What did you just come and ask me?" Shishuang started to raise his previous question when Daowu got up and left the room. Shishuang then had a great realization.' (Zen’s Chinese Heritage) I am not surprised Daowu left the room. Shishuang comes along with some hi-faluting question and then doesn't even notice the response that is given. No action replays in these old stories.
