3.1123

第四。初引文，犯重，即邊罪；邊尼並難，約過輕重，故得否兩殊。

The fourth: first, the citation states that committing a grave offense is a borderline transgression; borderline transgressions and [violating] a nun are both impediments, but depending on the gravity or lightness of the fault, attainment and non-attainment are different.
