Salhasutta 2.2

2.2

Yadā tumhe, sāḷhā, attanāva jāneyyātha ‘ime dhammā akusalā, ime dhammā sāvajjā, ime dhammā viññugarahitā, ime dhammā samattā samādinnā ahitāya dukkhāya saṃvattantī’ti, atha tumhe, sāḷhā, pajaheyyātha.

But when you know for yourselves: ‘These things are unskillful, blameworthy, criticized by sensible people, and when you undertake them, they lead to harm and suffering’, then you should give them up.
