瑜伽論記 13.18

13.18

今此分中兼明現行第八是六識通依，既是通依不可別開二地明之所以合說，從第八說故合一明，又唯約作業，作業既別，須開別明，俱依根緣塵，行相狀同，所以合說。又如顯揚第六云：問阿賴耶識何識所攝？

Now in this division, it concurrently clarifies that the active eighth consciousness is the common support of the six consciousnesses; since it is the common support, it cannot be clarified by opening them into two stages, which is why they are explained together. Being explained from the viewpoint of the eighth, they are combined into one to be clarified. Furthermore, if viewed solely in terms of initiating karma, since initiating karma is distinct, they must be opened and clarified separately; but both depend on faculties and take dusts as conditions, their modes of activity being similar, so they are explained together. Furthermore, as the sixth fascicle of the Prakaraṇāryavācā says: 'Question: Under which consciousness is the ālayavijñāna subsumed?'
