成唯識論述記 4.233

4.233

述曰：第四徵類同。中有二：初凡聖類同；後根、法類同。此初也，聖、異生心，識類同故。前成凡夫，後成阿羅漢。或是異身但類同者，應互相熏。諸阿羅漢為諸染熏，異生應為無漏法熏，是識類故，如自異生自聖者等。許便有失，無凡聖故。

The Commentary states: Fourth, investigating the identity of the category. Within this there are two: first, the identity of the category of noble and ordinary; second, the identity of the category of sense-faculties and dharmas. This is the first: because the minds of the noble and the ordinary person are of the same category of consciousness. Formerly one is an ordinary person, and later one becomes an arhat. Or, in different bodies that simply share the same category, they should mutually perfume each other. Arhats would be perfumed by defilements, and ordinary persons would be perfumed by uncontaminated dharmas, because they are of the category of consciousness, just like one's own ordinary person [state], one's own noble person [state], and so forth. If you accept this, there is an error, because there would be neither ordinary nor noble.
