Yo, bhikkhave, ime dhamme evaṁ saddahati adhimuccati, ayaṁ vuccati saddhānusārī, okkanto sammattaniyāmaṁ, sappurisabhūmiṁ okkanto, vītivatto puthujjanabhūmiṁ; abhabbo taṁ kammaṁ kātuṁ, yaṁ kammaṁ katvā nirayaṁ vā tiracchānayoniṁ vā pettivisayaṁ vā upapajjeyya; abhabbo ca tāva kālaṁ kātuṁ yāva na sotāpattiphalaṁ sacchikaroti. Yassa kho, bhikkhave, ime dhammā evaṁ paññāya mattaso nijjhānaṁ khamanti, ayaṁ vuccati: ‘dhammānusārī, okkanto sammattaniyāmaṁ, sappurisabhūmiṁ okkanto, vītivatto puthujjanabhūmiṁ; abhabbo taṁ kammaṁ kātuṁ, yaṁ kammaṁ katvā nirayaṁ vā tiracchānayoniṁ vā pettivisayaṁ vā upapajjeyya; abhabbo ca tāva kālaṁ kātuṁ yāva na sotāpattiphalaṁ sacchikaroti’.
