唯識二十論述記 2.25

2.25

述曰：自下第三，一一破執，先破外道，未破小乘，故言：且彼所執外境，理應非一。釋頌初句，此即總非，次顯非理。

Commentary: From here on is the third part, refuting the attachments one by one. First refuting the non-Buddhists before refuting the Hīnayāna, it therefore says: 'Moreover, that external object held [by them], by reason, cannot be one.' This explains the first line of the verse; this is a general negation, and next its unreasonableness is shown.
