俱舍論疏 28.176

28.176

論「此四唯是至以下劣故」，述唯借無記，不借染、善。生上已離下染，亦不起下劣善故。問：生上三定起下眼、耳二通，是何無記？有人云：唯是威儀心，或是緣威儀心，或似威儀心。皆謂不然，耳識不可是威儀心，發語表業亦不可說是威儀心，違多論故。若謂發語表業，是第二師，從威儀心更生意識，緣十二處，亦名威儀心故。此發語表心名威儀心者，此亦非理，豈可二定已上發語表業心皆從威儀心後起耶？若依第一師解，何得是威儀心？第一師唯以發威儀意識是威儀心。語既非威儀，何得是威儀？以此故知四無記心攝心不盡。既無記色攝色不盡，何妨四無記亦攝心不盡。問：既言四無記攝無記心不盡，未知借識是何無記？答：此借識心是自性無記。耳識非威儀，非威儀無記。上地無工巧，非工巧無記。變化唯在意，非變化無記。異熟非異地起，非異熟無記。以此故知唯是自性。

The passage of the śāstra from 'These four are only...' down to '...because they are inferior' explains that one borrows only the neutral (avyākṛta), not the defiled or the wholesome. Having been born above, one has already detached from the defilements of the lower stages, and one also does not give rise to inferior wholesome [minds]. Question: When one born in the upper three dhyānas gives rise to the lower two supernormal faculties of eye and ear, what kind of neutral mind is this? Some say it is solely the deportment mind (īryāpatha-citta), or a mind directed toward deportment, or resembling deportment. All these are not correct: the ear-consciousness cannot be a deportment mind, nor can the mind that produces vocal manifestative action be said to be a deportment mind, for that would contradict many treatises. If it is said that producing vocal manifestative action refers to the second master's position—where from the deportment mind a mental consciousness is further produced which takes the twelve sense-fields as its object, and is also called a deportment mind—and therefore this mind producing vocal manifestative action is called a deportment mind, this too is unreasonable. How could it be that above the second dhyāna the mind producing vocal manifestative action is in all cases produced subsequently to a deportment mind? If one relies on the first master's explanation, how could it be a deportment mind? The first master holds solely that the mental consciousness producing deportment is the deportment mind. Since speech is not deportment, how could it be deportment? From this it is known that the four neutral minds do not exhaust all minds. Since neutral form does not exhaust all form, what is there to prevent the four neutral types from also not exhausting mind? Question: Since you say that the four neutral minds do not exhaust neutral minds, we do not know what kind of neutral mind the borrowed consciousness is. Answer: This borrowed consciousness-mind is the intrinsically neutral (prakṛty-avyākṛta). Ear-consciousness is not deportment, so it is not deportment neutrality. The upper stages lack crafts, so it is not technical-craft neutrality. Transformations exist only in the mental consciousness, so it is not transformation neutrality. Ripened result is not produced from a different stage, so it is not ripened-result neutrality. Therefore it is known that it is solely the intrinsically neutral.
