5.117

言不淨生處超越因故者，三惡趣、八無暇名不淨生處，二淨業名超彼因，三牟尼業者則三善業，三法除不正尋中。謂由他所誹毀乃至所起慚愧，及愛敬者，於他所誹毀生愧顧他羞恥故，於自所誹毀生慚顧己羞恥故，退失大利深識因緣，倍生慚信名為愛敬，則於三寶無愛敬故名失大利，或於三處各能起三，不須別配。

Regarding 'because it is the cause of transcending impure birthplaces': the three bad destinies and the eight conditions lacking leisure are called impure birthplaces; the two pure karmas are called the cause of transcending them. The three muni karmas are the three wholesome karmas. In 'three dharmas for eliminating improper thoughts': regarding 'due to others' reproach... up to the shame and respect generated': towards others' reproach one generates embarrassment, feeling shame with regard to others; towards one's own reproach one generates moral shame, feeling shame with regard to oneself. Losing great benefit and deeply understanding causes and conditions, one generates double shame and faith, which is called love and respect; thus having no love and respect for the Three Jewels is called losing great benefit. Or alternatively, one can generate all three at each of the three places, without needing to match them individually.
