Chan Meditation Koan

The master grabbed the front of his disciple's robe and asked: Does the Buddha-dharma corrupt or destroy worldly dharmas?

The disciple slammed his fist on the table and pushed the master away.

The master glared at the disciple, then turned around and walked off with his hands behind his back.

Question: Did the disciple answer the master's question? If he did, how did he answer it? When the master turned and walked away, was he satisfied or dissatisfied?

Regarding this koan, A, B, C, and D engaged in all sorts of debates. The master said: 穷诸玄辩，若一豪置于太空，讲一藏经，不如一巴掌拍去。
