成唯識論了義燈 2.18

2.18

釋作業受果，大乘八識以辨有無。前六具二；第七俱無、無記故，不作業，染污故，非受果；第八受果是異熟，異熟故，不能作業，無記性故。犢子、正量、本經、賢胄、密林山等五部。同說五識不能作業、受果，第六並能。大眾部等，同說六識並能作業、受果。薩婆多等，五識受果，而不作業。第六俱能（此釋，傳聞未見正教）。

Explaining the performance of karma and the reception of retribution: the Mahāyāna distinguishes presence and absence among the eight consciousnesses. The first six possess both; the seventh lacks both: because it is indeterminate, it does not perform karma, and because it is defiled, it does not receive retribution; the eighth receives retribution, being fruition: because it is fruition, it cannot perform karma, its nature being indeterminate. The five schools—Vātsīputrīya, Sammatīya, Mūlasūtra, Bhadrayānīya, and Ṣaṇṇagarika—uniformly say that the five consciousnesses cannot perform karma or receive retribution, while the sixth can do both. The Mahāsāṃghika and others uniformly say that all six consciousnesses can both perform karma and receive retribution. The Sarvāstivādins and others hold that the five consciousnesses receive retribution but do not perform karma, while the sixth can do both. (This explanation is hearsay; I have not seen authentic textual authority.)
