The Long Āgama Sūtra 12.7

12.7

佛告比丘：「三法聚者，一法趣惡趣。一法趣善趣。一法趣涅槃。云何一法趣于惡趣？謂無仁慈，懷毒害心，是謂一法將向惡趣。云何一法趣于善趣？謂不以惡心加於眾生，是為一法將向善趣。云何一法趣于涅槃？謂能精勤，修身念處，是為一法將向涅槃。

The Buddha addressed the monks, “These three categories are one thing that leads to bad destinies, one thing that leads to good destinies, and one thing that leads to Nirvāṇa.

“What’s one thing that leads to bad destinies? It’s the absence of kindness that harbors harmful thoughts. This is one thing that leads to bad destinies.

“What’s one thing that leads to good destinies? It’s not inflicting bad intent on sentient beings. This is one thing that leads to good destinies.

“What’s one thing that leads to Nirvāṇa? It’s making effort to cultivate the abodes of mindfulness. This is one thing that leads to Nirvāṇa.
