成唯識論述記 10.320

10.320

述曰：六識俱者，八地不行，以二空無漏無分別智心及此果、滅定、後得智等，相續不斷能違第六識二執，故不行。

[The Commentary states:] Those concomitant with the sixth consciousness do not operate on the eighth ground, because the uncontaminated, non-conceptual wisdom of the two emptinesses and its fruits, the cessation absorption, the post-attainment wisdom, and so forth, continuously without interruption, can oppose the two graspings of the sixth consciousness, and therefore they do not operate.
