成唯識論演祕 3.237

3.237

有義又說，此中破安惠義，雖解此是二分，非三分文，如何說彼無能緣耶？自證即是能緣用故。故於二分，但可破彼無所緣相或可。此文非二分義，即是三分。

One interpretation further states: As for the refutation of Sthiramati's doctrine here, although this is explained as the text of the two aspects and not the three aspects, how can it be said that he lacks that which is capable of cognizing? Because self-awareness is itself the function capable of cognizing. Therefore, with respect to the two aspects, one could only refute his lack of an image-aspect; or perhaps this text is not the doctrine of two aspects, but rather the three aspects.
