四分律行事鈔資持記 3.1109

3.1109

三中，《四分》制六法緣。行，合作形，字設。《十誦》，制二年緣。起過，謂生子招譏。

In the third part, the Dharmaguptaka-vinaya gives the origin of formulating the six dharmas. For 'xing' (conduct), it should properly be 'xing' (bodily form), an established character. The Daśādhyāya-vinaya gives the origin of formulating the two years. 'Arising of faults' means giving birth to a child and attracting criticism.
