Santakāyo santavāco, santavā susamāhito;Vantalokāmiso bhikkhu, upasantoti vuccati.
Santakayo santavaco, santava susamahito; Vantalokamiso bhikkhu, upasantoti vuccati.
Peaceful in body, peaceful in speech, peaceful in mind and well-concentrated — the bhikkhu who has rejected worldly enticement is called 'one at peace.'
