Dhammapada · 26.8
Na brāhmaṇassetadakiñci seyyo, yadā nisedho manaso piyehi;Yato yato hiṃsamano nivattati, tato tato sammatimeva dukkhaṃ.
Na brahmanassetadakinci seyyo, yada nisedho manaso piyehi; Yato yato himsamano nivattati, tato tato sammatimeva dukkham.
Nothing is better for a brahmin than holding back the mind from what is dear. Whenever the will to hurt is given up, suffering ceases.
