Dhp 193 Ānandattherapañhavatthu
The Provenance of the Buddhas
The Buddha taught this verse in answer to a question by Venerable Ānanda.
62. Dullabho Purisājañño, na so sabbattha jāyati,
Yattha so jāyate Dhīro, taṁ kulaṁ sukham-edhati.
A Buddha is rare in the world,
He is not born just anywhere,
Wherever the Wise One is born,
That family gains happiness.
