3.68

五修非三非者，五謂信等五根，通修、非二斷，若有漏者是修所斷，若無漏者是非所斷。不染污故，不通見斷。三無漏根唯非所斷，非無漏法，是所斷故。已上是第四，諸門分別竟。

'Five are cultivation and non-abandoned; three are non-abandoned': 'five' refers to the five faculties beginning with faith, which admit of the two abandonments of cultivation and non-abandonment; if defiled, they are abandoned by cultivation, and if undefiled, they are not to be abandoned. Because they are not defiled, they do not admit of abandonment by seeing. The three undefiled faculties are exclusively not to be abandoned, because whatever is not an undefiled phenomenon is what is to be abandoned. The above concludes the fourth [major topic], the differentiation through various doors.
