大般涅槃經集解 39.104

39.104

案僧亮曰：說佛無常，凡夫謂實，是第一也。說第一義，眾生謂佛說於世諦者，佛說常樂是第一義，凡夫便謂假，是世諦也。寶亮曰：近而取之，假名實法空皆是世諦；遠而取之，九地以來所得無我空者亦是世諦，唯有涅槃體常寂滅為真諦耳。而物情所謂九住以還得空，負第一義，論理悉是世諦也。

Sengliang says: When speaking of the Buddha as impermanent, ordinary persons consider it real, taking it as ultimate. As for 'speaking of the ultimate truth, sentient beings consider the Buddha to be speaking of conventional truth': when the Buddha speaks of permanence and bliss as the ultimate truth, ordinary persons then consider it provisional, taking it as conventional truth. Baoliang says: Taken nearby, the emptiness of provisional designations and real dharmas are all conventional truth; taken from afar, the emptiness of non-self attained from the ninth bhūmi down is also conventional truth; only the essence of nirvāṇa, permanently quiescent, is the true truth. Yet what worldly sentiments consider as attaining emptiness from the ninth dwelling down and bearing the ultimate truth, according to principle, are entirely conventional truth.
