成唯識論述記 3.136

3.136

問：何故彼復說第八識頓分別知一切境界？答：說自一切境，皆頓分別知，非如餘識境漸次能了故。由是彼經復作是說：自身及資具，一時頓分別，與此文同，並不違也。問：何故《辨中邊》云：唯緣根、塵，生覺受故，舊論云：根塵我及識，本識生似彼，至卷末當解。

Question: Why does that sūtra further state that the eighth consciousness immediately and discriminatively knows all realms of objects? Answer: It states that it immediately and discriminatively knows all of its own objects, unlike other consciousnesses whose objects are discerned gradually. Therefore, that sūtra further states: 'One's own body and requisites are immediately and simultaneously discriminated,' which is identical with this text and does not conflict at all. Question: Why does the Madhyāntavibhāga state: 'It takes only faculties and dusts as objects, because they produce sensory feelings,' and the older translation of the treatise states: 'Faculties, dusts, self, and consciousness—the root consciousness arises resembling them'? This will be explained at the end of the fascicle.
