大般涅槃經集解 33.4

33.4

案僧亮曰：上以問真，次問四倒。若不入四諦，實諦攝法不盡，下訖佛說亦爾。一道以下不難攝實不周，乃則說實不濫耳。法瑤曰：上來明四諦皆名為實諦，似如顛倒虛妄，非苦集諦所攝，是以發此問也。寶亮曰：釋第二境實也。問四諦中有倒不若有者，云何言實？若四諦無，則四諦之外應更有法也。

Sengliang states: Above, having inquired about the true, he next inquires about the four inversions. If they do not enter the four truths, then the real truth does not subsume all dharmas; below, down to the Buddha's explanation, it is also like this. From 'the one path' onward, it does not challenge that the subsumption of the real is not comprehensive; rather, it ensures that the explanation of the real is not confused. Fayao states: The preceding text clarified that the four truths are all called real truths, which seemed to suggest that inversions and false errors are not subsumed under the truths of suffering and origination; therefore this question was raised. Baoliang states: Explaining the second, the reality of the object. He asks whether there are inversions within the four truths; if there are, how can they be called real? If the four truths lack them, then outside the four truths there should be further dharmas.
