Dhp 386-388 · The Brahmana (Arhat)
He who is thoughtful, blameless, settled, dutiful, without passions, and who has attained the highest end, him I call indeed a Brahmana. The sun is bright by day, the moon shines by night, the warrior is bright in his armour, the Brahmana is bright in his meditation; but Buddha, the Awakened, is bright with splendour day and night. Because a man is rid of evil, therefore he is called Brahmana; because he walks quietly, therefore he is called Samana; because he has sent away his own impurities, therefore he is called Pravragita (Pabbagita, a pilgrim).
