瑜伽論記 15.8

15.8

Second, it clarifies that the conceptualizing mental consciousness and the non-conceptual five consciousnesses cognize the present object together. There are three causes and conditions to explain this: First, being extremely clear: because that mental consciousness apprehends the present object together with the five consciousnesses, the mental consciousness apprehends each clearly with respect to the object. Second, because of attention directed toward it: because root attention desires to grasp the present object, the mental consciousness co-arising with the five consciousnesses cognizes that form together [with them]. Third, because of nourishment from two supports: that mental consciousness, on the one hand, relies on the mental faculty, namely manas. On the other hand, it also receives nourishment by relying on the eye faculty: because that visual consciousness discerns form relying on the eye, it enables that mental consciousness to grasp the object distinctly; therefore, the eye faculty also provides nourishment to that mental consciousness, hence it is said to have 'nourishment from two supports.'"
