成唯識論演祕 5.591

5.591

此有二意：一、成有事緣第一釋；二、成無漏必約影、質不可，以彼有事緣中，初釋相例。

This has two meanings: first, to establish the first explanation of taking things with real facts as objects; second, to establish that taking anāsrava as object must refer to both image and mūla-dharmin, and cannot be analogized to the first explanation under taking things with real facts as objects.
