俱舍論記 18.157

18.157

「若具四德至非勝生故」者，釋下兩句。若具四德，得清淨名，此釋淨字。若不具德，名不清淨。言四德者，一者不為犯戒所壞，犯戒謂前諸不善色，此釋非犯戒壞。二者不為彼犯戒因所壞，彼因謂貪等，此釋非因壞。三者何依治，謂依四念住、四正斷等，此念住等能對治彼犯戒及因，此釋依治。四者依滅，謂依涅槃，願以持戒所生功德迴向涅槃，非求人、天二勝生故，此釋依滅。

"If endowed with four virtues ... because it is not for superior rebirth": this explains the lower two lines. If endowed with four virtues, it attains the name "pure"; this explains the word "pure." If not endowed with these virtues, it is called "impure." As for the four virtues: first, not being ruined by the transgression of morality—transgression of morality refers to the aforementioned unvirtuous corporeal forms; this explains "not ruined by transgression of morality." Second, not being ruined by the causes of that transgression of morality—those causes refer to greed and so forth; this explains "not ruined by its causes." Third, what does it rely on as an antidote? It means relying on the four applications of mindfulness, the four right strivings, and so forth; these applications of mindfulness and so forth can serve as antidotes to that transgression of morality and its causes; this explains "relying on antidotes." Fourth, relying on cessation: that is, relying on nirvāṇa, wishing to dedicate the merits produced by upholding morality toward nirvāṇa, because it is not for seeking the two superior rebirths of humans and devas; this explains "relying on cessation."
