26: The Chapter about Brahmins – 352
The one whose destiny is unknown
The youth Vaṅgīsa could tell where anyone had been reborn
by knocking on their skulls; the Buddha set out the skull of an
Arahat before him and he was unable to see where he had
been reborn, so he ordained to learn about it; soon he became
an Arahat himself and the Buddha confirmed he now knew all
about the rebirth of beings.
419. Cutiṁ yo vedi sattānaṁ upapattiñ-ca sabbaso,
asattaṁ sugataṁ buddhaṁ, tam-ahaṁ brūmi brāhmaṇaṁ.
Whoever knows in ev’ry way
beings’ passing and their rebirth,
unattached, fortunate, awake,
that one I say is a brahmin.
420. Yassa gatiṁ na jānanti devā gandhabbamānusā –
khīṇāsavaṁ Arahantaṁ, tam-ahaṁ brūmi brāhmaṇaṁ.
For the one whose destiny is
unknown to gods, gandhabbas, men –
pollutant-free, an Arahat,
that one I say is a brahmin.
