成唯識論述記 4.337

4.337

述曰：下明執心顯唯第八於中有二：一、顯八有七無；二、簡言濫。此初文也。何心能執受？唯異熟心，謂第八識。先業所引，體任運起，非現緣起。縱第七識亦現緣引，不能執受。即是八證執受五因中第一因，下自為量，不能煩述。非善、染等，等取威儀等無記，彼是第二因；彼言六識善、惡可得故，不能執受。一類，謂第八識一類異熟無記性攝，次第三因；彼言六識一類異熟無記性攝不可得故，不能執受。能遍執受者，謂唯本識遍能執受五根等法，是第四因；彼言六識各別依故，不能遍執。此中第八佛色根證如下自解，相續執受。謂第八識一切時執，非有執、不執。不執時即爛壞故，是第五因。彼言六識所依應成數數執受過失，唯第八識具此五義。眼等七種轉識皆非業引，不具五義故非能執。

The Commentary states: Below explains the appropriating mind, demonstrating that it is only the eighth. In this there are two parts: first, revealing that the eighth has it while the seven lack it; second, clarifying ambiguities in expression. This is the first passage. Which mind is capable of appropriation? Only the mind of retribution, namely the eighth consciousness. Drawn by past karma, its essence arises spontaneously, not arising from present conditions. Even if the seventh consciousness were also drawn by present conditions, it could not appropriate. This is the first reason among the five reasons for appropriation in the eight proofs; below [the treatise] will formulate formal inferences (prayogamāna) itself, so there is no need to laboriously describe them here. "Not wholesome or defiled, etc."—"etc." includes indeterminate [minds] such as deportment; that is the second reason. It means that because wholesomeness and unwholesomeness can be found in the six consciousnesses, they cannot appropriate. "Of one continuous nature" means that the eighth consciousness is subsumed under one continuous nature of retribution-indeterminate; this is the third reason. It means that because being subsumed under one continuous nature of retribution-indeterminate cannot be found in the six consciousnesses, they cannot appropriate. "Capable of all-pervading appropriation" means that only the root consciousness can pervade and appropriate the five faculties and other phenomena; this is the fourth reason. It means that because the six consciousnesses have distinct bases, they cannot pervade and appropriate. Here, the proof regarding the Buddha's material faculties will be explained below. "Continuous appropriation" means that the eighth consciousness appropriates at all times, not having appropriation at some times and non-appropriation at others. For when it does not appropriate, [the body] decays; this is the fifth reason. It means that the bases of the six consciousnesses would incur the fault of repeated appropriation. Only the eighth consciousness is endowed with these five characteristics. The seven transforming consciousnesses such as the eye [consciousness] are none of them drawn by karma, and because they lack the five characteristics, they are not capable of appropriating.
