俱舍論記 2.55

2.55

「由五識身至名為無足」者，三分別中，五識有一無二，從多分說，名無分別。喻況可知。自性分別，五識必有，雖有慧、念而非分別。故《正理》第四云「五識雖與慧、念相應，擇、記用微，故唯取意。」又《婆沙》四十二云「欲界五識身唯有一種自性分別。雖亦有念，而非隨念分別，不能憶念故。雖亦有慧，而非推度分別，不能推度故（准《婆沙》文，隨所更事名為隨念。計度、推度名異義同）。」

Regarding "Because the five consciousness-bodies... are called legless": Among the three conceptualizations, the five consciousnesses possess one and lack two; speaking in terms of the majority, they are called "non-conceptual." The analogy is understandable. The five consciousnesses necessarily possess intrinsic conceptualization; although they have discernment (prajñā) and mindfulness (smṛti), these are not conceptualizations. Therefore the fourth fascicle of the *Nyāyānusāra* says: "Although the five consciousnesses are associated with discernment and mindfulness, their functions of discrimination and recollection are subtle, so [these conceptualizations] are taken only as mental consciousness." Furthermore, fascicle forty-two of the *Mahāvibhāṣā* says: "The five consciousness-bodies of the desire realm possess only one kind, intrinsic conceptualization. Although they also possess mindfulness, it is not conceptualization by recollection, because they cannot remember. Although they also possess discernment, it is not conceptualization by deliberation, because they cannot deliberate (inferring from the *Mahāvibhāṣā* text, following past experiences is called recollection; 'reckoning' and 'deliberation' differ in name but are identical in meaning)."
