成唯識論述記 1.445

1.445

述曰：下有五難：第一，既云各有三相，還應見三，如何見一？大等法中應見三相；相即體故；猶如三體。大等諸相或應見九；即本相故；如三體上所有九相。各三相故，不應見一；如前見色。此中一一更互為量，准為之也。

The Commentary states: Below are five challenges. First: Since they say that each has three marks, one should still perceive three; how could one perceive one? In phenomena such as mahat, one should perceive three marks, because the marks are identical with the substance, just as the three substances [are distinct]. Or, in the marks of mahat and so forth, one should perceive nine, because they are identical with the original marks, like the nine marks that exist upon the three substances. Because each possesses three marks, one should not perceive them as one, just as previously [established regarding] the perception of form. Here, one makes syllogisms reciprocally for each, following this pattern.
