5: The Discourse about the Elders
Thus I heard:
at one time the Fortunate One was dwelling near Sāvatthī, in Jeta’s Wood, at Anāthapiṇḍika’s monastery.
Then at that time venerable Sāriputta, venerable Mahāmoggallāna, venerable Mahākassapa, venerable Mahākaccāyana, venerable Mahākoṭṭhita, venerable Mahākappina, venerable Mahācunda, venerable Anuruddha, venerable Revata, and venerable Nanda went to the Fortunate One.
The Fortunate One saw those venerable ones coming while still far away, Wijesekera, Syntax §131c has shown that
After that was said, a certain monk who was a brāhmaṇa by birth, said to the Fortunate One: “To what extent, dear Gotama, is one a brāhmaṇa? And again what things make one a brāhmaṇa?”
Then the Fortunate One, having understood the significance of it, on that occasion uttered this exalted utterance:
“Those who, having removed bad things, live always mindful,
The Buddhas who have destroyed the fetters, truly they are brāhmaṇas in the world.”
