俱舍論疏 24.8

24.8

The treatise says, "For what reason in this case is there no... because they have not crossed the realm." This resolves an objection: For what reason does one who progresses toward the once-returner, upon abandoning five, definitely abandon six, whereas one who progresses toward the non-returner may abandon eight without abandoning nine? In this case one has not yet crossed the realm, whereas in that case one crosses the realm, which forms an extreme obstacle; therefore it is possible to abandon eight without abandoning nine.
