Dhammapada · 13.3
Dhammaṃ care sucaritaṃ, na naṃ duccaritaṃ care;Dhammacārī sukhaṃ seti, asmiṃ loke paramhi ca.
Dhammam care sucaritam, na nam duccaritam care; Dhammacari sukham seti, asmim loke paramhi ca.
Live the Dhamma well, not wrongly. The Dhamma-farer sleeps happily in this world and the next.
