四分律刪繁補闕行事鈔 3.427

3.427

二明懺罪法。初篇有犯，無覆、有悔，亦開懺悔；同僧懺法。二篇一法，覆藏全無；六夜，改僧制限半月。以尼女弱，情垢既多，要假大僧，受隨皆爾。若欲懺者，二部中行，各滿四人，半月悔過；及至出罪，各具二十。但道風漸替，知犯，不知有悔；縱有懺心，集眾難得；故闕而不載。偷蘭已下，乃至吉羅，各有懺儀，如中卷列；唯當部自結，稱名大姊為異；餘辭並同。

Second, explaining the method of confessing offenses. If an offense is committed in the first class [pārājika], if it was unhidden and there is repentance, confession is also allowed, the same as the method of confession for monks. As for the single method of the second class [saṃghāvaśeṣa], there is entirely no concealing: the six nights are changed to half a month according to the regulation for nuns. Because nuns are female and weak, and their emotional defilements are many, they must rely on the great monks; this is so for both receiving [the precepts] and following [them]. If she wishes to confess, she carries it out in both assemblies, each fulfilling four persons, for half a month of penance; and when it comes to rehabilitation, each [assembly] must comprise twenty. However, as the style of the Way has gradually declined, they know how to offend but do not know repentance; even if there is a mind to repent, assembling the community is difficult to achieve; therefore it is omitted and not recorded here. From sthūlātyaya on down to duṣkṛta, each has a confession ritual, as listed in the middle fascicle; the only difference is that it is concluded within their own assembly, addressing [the other] as "elder sister"; the remaining wording is completely identical.
