四分律行事鈔資持記 2.34

2.34

對尼中。後四如別，即〈別行篇〉；謂摩觸、八事、覆重、隨舉，女流報弱，情多喜犯；故枝條之罪，例同重制。

In the comparison with nuns: 'The latter four are as in the separate [section]' refers to the 'Chapter on Separate Practices'; that is, rubbing and touching, the eight acts, concealing a major [offense], and following one who has been suspended. The retribution of women is weak, and their disposition is prone to violations; therefore, the offences of the branches are regulated like the major ones by rule.
