俱舍論頌疏論本 18.134

18.134

下兩句者，明戒四德：一、非犯戒壞，離前犯戒也。二、不為犯戒因壞，因者，謂貪等煩惱也。三、依治者，治謂四念住等，治前犯戒及彼因故。四、依滅者，滅謂涅槃，迴向涅槃，非勝生故（人天生也）。頌言淨者，具上四德，戒名清淨，與此相違名不清淨。等者，復有異說：戒淨由五種因：一、根本淨，離惡根本也。二、眷屬淨，離惡方便也。三、非尋害，離惡覺也。四、念攝受，念受三寶也。五、迴向寂，求涅槃也。

The lower two lines explain the four virtues of morality. First, not being ruined by transgression: being free from the aforementioned transgressions of morality. Second, not being ruined by the causes of transgression: "causes" refers to defilements such as greed. Third, "relying on antidote": "antidote" refers to the four applications of mindfulness and so forth, because they counteract the aforementioned transgressions of morality and their causes. Fourth, "relying on cessation": "cessation" refers to nirvāṇa; dedicating towards nirvāṇa, not towards superior rebirth (rebirth among humans and devas). The verse says "pure": endowed with the four virtues above, morality is called pure; contrary to this, it is called impure. "Etc." means there is another explanation: the purity of morality is due to five kinds of causes: first, purity of the fundamental, being free from evil fundamentals; second, purity of the retinue, being free from evil expedients; third, not being harmed by discursive thought, being free from evil thoughts; fourth, being embraced by mindfulness, mindfully receiving the Three Jewels; fifth, dedicating towards tranquility, seeking nirvāṇa.
