2.133

差別者，一五乘差別有二：初立差別；後問答辨。且決定大乘，具依二障未永斷位分別種，立大乘異生性。若所知障畢竟不可害，非煩惱者，依此煩惱，一分立為聲聞定性異生性，一分立為獨覺定性異生性，以樂觀諦、十二因緣，悟證、依待二性別故。若俱不可斷，依斯立為無性乘異生性。

Regarding the distinctions: first, the distinctions among the five vehicles are twofold: first, establishing the distinctions; second, analyzing them through questions and answers. First, for those determinate in the Mahāyāna, the ordinary nature of the Mahāyāna is established comprehensively based on the differentiated seeds at the stage where the two obstructions have not yet been perpetually severed. If the obstruction to knowables is ultimately indestructible, but the affliction [obstruction] is not, then on the basis of a portion of these afflictions is established the ordinary nature of those determinate in the Śrāvaka [lineage], and on the basis of a portion is established the ordinary nature of those determinate in the Pratyekabuddha [lineage], because their inclinations toward contemplating the truths or the twelve links of dependent arising, as well as their awakenings and realizations, depend upon two distinct natures. If both are indestructible, based on this is established the ordinary nature of the vehicle lacking lineage.
