四分律刪繁補闕行事鈔 2.442

2.442

若準此義，犯不犯位，亦有三別。如上重輕，應本定五；進就不犯故，即成或四五者。今犯不犯，如盜戒中，本是或四五；今退就犯中，對非畜二物作想，轉迷俱五，亦成三位。

According to this meaning, the positions of transgression and non-transgression also have three distinctions. As in the above grave and light, it should originally be fixed as five; proceeding toward non-transgression, it becomes either four or five. Now in transgression and non-transgression, as in the precept against theft, it was originally either four or five; now retreating into transgression, making ideation toward non-human and animal objects, shifting and bewilderment both have five, also forming three positions.
