成唯識論述記 5.246

5.246

述曰：答中有二：初舉頌答；後廣分別。此即初也。「不爾」、「故」三字釋者加也，非唯有四，故言「不爾」。頌有「餘」字遂有諍生，下有二解「餘」字。即為二文：一謂四惑之餘，即次第一解是；二謂觸等之餘，即下四師解是。

The Commentary states: In the reply there are two parts: first, citing the verse in reply; later, explaining in detail. This is the first part. The three words "It is not so" and "because" are added by the commentator; it does not only have four, hence it states "It is not so." Because the verse has the word "rest" (yú), disputes arose; below are two explanations of the word "rest." These form two passages: first, meaning the rest of the four defilements, which is the immediate first explanation; second, meaning the rest of contact and so forth, which is the explanation of the four masters below.
