Meditative Concentration Koan

The master grabbed the front lapel of his disciple's robe and asked: Does the Buddha-dharma destroy or not destroy worldly dharma?

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

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

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

Regarding this koan, various people — A, B, C, and D — debated in all sorts of ways. 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。
