大般涅槃經集解 32.22

32.22

案道生曰：理無二實而有二名，如其相有，不應設二；如其相無，二斯妄矣。法瑤曰：將明二諦名異而實同，故第一義之實即有世諦之實，即有第一義。是以問二諦之實可得相有不耳，不問二名之義可得相有。

Daosheng notes: "In principle there are no two realities, yet there are two names. If they exist in their marks, two should not be posited; if they are devoid of marks, the two are illusory." Fayao says: "About to clarify that the two truths differ in name but are identical in reality, the reality of the ultimate truth is thus having the reality of the conventional truth, and [the conventional truth] thus has the ultimate truth. Hence it is asked whether the realities of the two truths can mutually exist, not whether the meanings of the two names can mutually exist."
