Dhammapada · 10.4

Sukhakāmāni bhūtāni, yo daṇḍena na hiṃsati;Attano sukhamesāno, pecca so labhate sukhaṃ.

Sukhakamani bhutani, yo dandena na himsati; Attano sukhamesano, pecca so labhate sukham.

One who, seeking his own happiness, does not harm beings desiring happiness — that one obtains happiness hereafter.
