瑜伽論記 5.356

5.356

於中初一頌明所離惑，即是末那與四惑俱同生同滅。非先、亦非後者，金剛道起染意四惑俱時而斷，故無先後。又非先者末那與惑恒俱生故；非後者，即與彼惑俱時滅故。後釋符順長行也。

Among them, the first verse clarifies the afflictions to be abandoned, namely manas co-arising and co-ceasing together with the four afflictions. Regarding "neither before nor after": when the adamantine path arises, the defiled mental faculty and the four afflictions are severed simultaneously, so there is no before and after. Furthermore, "not before" means that manas always co-arises with afflictions; "not after" means that it ceases simultaneously with those afflictions. The latter interpretation accords with the prose.
