Doṇa, the ancient brahmin seers were Aṭṭhaka, Vāmaka, Vāmadeva, Vessāmitta, Yamadaggi, Aṅgīrasa, Bhāradvāja, Vāseṭṭha, Kassapa, and Bhagu. They were the authors and propagators of the hymns, whose hymnal was sung and propagated and compiled in ancient times. These days, brahmins continue to sing and chant it. They continue chanting what was chanted, rehearsing what was rehearsed, and teaching what was taught.
Those seers described five kinds of brahmins. A brahmin who is equal to the Divinity, one who is equal to a god, one who toes the line, one who crosses the line, and the fifth is a brahmin corpse-worker. Which one of these are you, Doṇa?”
“This being so, worthy Gotama, I don’t even qualify as a brahmin corpse-worker.
Excellent, worthy Gotama! … From this day forth, may the worthy Gotama remember me as a lay follower who has gone for refuge for life.”
Numbered Discourses 5.193 20. Brahmins With Saṅgārava
Then Saṅgārava the brahmin went up to the Buddha, and exchanged greetings with him. When the greetings and polite conversation were over, Saṅgārava sat down to one side, and said to the Buddha:
“What is the cause, Worthy Gotama, what is the reason why sometimes even hymns that are long-rehearsed don’t spring to mind, let alone those that are not rehearsed? And why is it that sometimes even hymns that are long-unrehearsed spring to mind, let alone those that are rehearsed?”
