Not to do any evil, to cultivate good, to purify one's mind, this is the Teaching of the Buddhas.
Khantī paramaṁ tapo titikkhā, Nibbānaṁ paramaṁ vadanti Buddhā, na hi pabbajito parūpaghātī, samaṇo hoti paraṁ viheṭhayanto.
Forbearing patience is the highest austerity. Nibbàna is supreme, say the Buddhas. He, verily, is not a recluse who harms another. Nor is he an ascetic who oppresses others.
Anupavādo anupaghāto, pātimokkhe ca saṁvaro, mattaññutā ca bhattasmiṁ, pantañ-ca sayanāsanaṁ, adhicitte ca āyogo - etaṁ Buddhāna’ sāsanaṁ.
Not insulting, not harming, restraint according to the Fundamental Moral Code, moderation in food, secluded abode, intent on higher thoughts, - this is the Teaching of the Buddhas.
