3.68

'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.
