The Long Āgama Sūtra 9.16

9.16

「復有四法，謂四刺：欲刺、恚刺、見刺、慢刺。復有四法，謂四生：卵生、胎生、濕生、化生。復有四法，謂四念處；於是，比丘內身身觀，精勤不懈，憶念不忘，捨世貪憂；外身身觀，精勤不懈，憶念不忘，捨世貪憂；內外身身觀，精勤不懈，憶念不忘，捨世貪憂。受、意、法觀，亦復如是。復有四法，謂四意斷；於是，比丘未起惡法，方便使不起；已起惡法，方便使滅；未起善法，方便使起；已起善法，方便思惟，使其增廣。

He’s mindful, not forgetful, and casts off worldly craving and sadness … observes internal and external body as body diligently and not negligently. He’s mindful, not forgetful, and casts off worldly craving and sadness. He observes [2] feelings, [3] mind, and [4] principles in the same way.

“There are another four things, which are four mental abandonments: Here, a monk applies effort to make bad qualities that have yet to arise to not arise … applies effort to make bad qualities that have arisen to cease … applies effort to make good qualities that have yet to arise to arise … applies effort to make good qualities that have arisen to increase.
