Dhammapada · 24.17

Vitakkūpasame ca yo rato, asubhaṃ bhāvayate sadā sato;Esa kho byanti kāhiti, esa checchati mārabandhanaṃ.

Vitakkupasame ca yo rato, asubham bhavayate sada sato; Esa kho byanti kahiti, esa checchati marabandhanam.

But one who delights in the calming of thoughts, who cultivates the foul, ever mindful — he indeed will make an end; he will cut Māra's bond.
