俱舍論記 10.101

10.101

「謂有三地至非本所誦」者，經部答。若法於前有尋伺等，諸地皆有，名大地法，非要與心同一剎那俱時而生名大地法。義便兼解大善地法等。所以不釋大不善地法者，有餘師說：如是大不善地法，但是後代毘婆沙師因誦大善故引不善來。是今所增益，非本論所誦，故不別釋。所以不釋少煩惱者，以非遍故。

Regarding "That is, there are three stages … not in the original recitation": the Sautrāntika answers. If a dharma exists in all stages, such as those with investigation and reflection mentioned earlier, it is called a universal mental factor; it is not called a universal mental factor because it must arise simultaneously with the mind in the very same moment. As it fits the context, it also incidentally explains the great wholesome ground dharmas and so forth. The reason it does not explain the great unwholesome ground dharmas is that other masters say: such great unwholesome ground dharmas were merely brought in by later masters of the Vibhāṣā by analogy when reciting the great wholesome [ground]. It is a recent addition and not in the recitation of the fundamental treatises, so it is not separately explained. The reason it does not explain the secondary afflictions is that they are not pervasive.
