--Any question?--

One day Te-shan gave a sermon, in which he said, "When you question, you commit a fault.  When you do not, you give offense."

A monk came forward and began to bow, whereupon the master struck him. 

"I have just begun my bowing!"  said the monk.  "Why did you strike me?"

"If I wait for you to open your mouth, all will be over."
