10. Seizei Alone and Poor

A monk named Seizei asked of Sozan: "Seizei is alone and poor. Will you give him support?"

Sozan asked: "Seizei?"

Seizei responded: "Yes, sir."

Sozan said: "You have Zen, the best wine in China, and already have finished three cups, and still you are saying that they did not even wet your lips."

Mumon's comment: Seizei overplayed his hand. Why was it so? Because Sozan had eyes and knew with whom to deal. Even so, I want to ask: At what point did Seizei drink wine?
