大般涅槃經集解 32.20

32.20

案僧亮曰：為義一名異、為名義俱異耶？僧宗曰：上明四諦其義則狹，今說二諦其理則廣，皆是智境也。所以言四諦狹者，猶此是世諦道中分別為四，今第一義蘯於前四也。又且虛空及非數緣滅不在四諦中攝，今以二諦而收，則是世諦攝也。智秀曰：將顯二諦，先設一問二難也。此即第一問二諦體相也。

Sengliang notes: "Is the meaning one and the names different, or are both names and meanings different?" Sengzong says: "Above, the meaning of the four truths was narrow; now, when the two truths are explained, their principle is broad—both being the cognitive objects of wisdom. The reason the four truths are called narrow is that they are distinctions made into four within the path of conventional truth, whereas the ultimate truth now clears away the preceding four. Moreover, space and cessation not through deliberation are not subsumed within the four truths, yet when subsumed by the two truths, they fall under the conventional truth." Zhixiu says: "About to clarify the two truths, one question and two dilemmas are first posited. This is the first question on the essential nature and marks of the two truths."
