7.73

下正答之，「聞所不聞亦復如是」者總舉類前，次列四名，義如上解。問曰：此四云何答上德王六難？釋言：德王難別三對，一一對中義皆有四，兩立兩破：一立聞聞、二即約此難破如來聞不聞義、三立不聞不聞、四即約此難破如來不聞聞義。佛今隨其所立所破並為存之，故列四門以答上難。

Below, he directly answers it. The phrase "hearing what has not been heard is also like this" brings together the analogy with the preceding; next he lists four designations, the meaning of which is as explained above. Question: How do these four answer King of Virtue's six objections above? Explanation: King of Virtue's objections are distinguished into three pairs, and within each and every pair there are four points, two establishing and two refuting: first, establishing hearing what is heard; second, relying on this to challenge and refute the Tathāgata's meaning of hearing what is not heard; third, establishing not hearing what is not heard; fourth, relying on this to challenge and refute the Tathāgata's meaning of not hearing what is heard. The Buddha now retains them all in accordance with what he established and what he refuted, and therefore sets forth four approaches to answer the objections above.
