Tathāgatassa, bhikkhave, arahato sammāsambuddhassa pātubhāvo dullabho lokasmiṁ, tathāgatappaveditassa dhammavinayassa desetā puggalo dullabho lokasmiṁ, kataññū katavedī puggalo dullabho lokasmiṁ. Imesaṁ kho, bhikkhave, tiṇṇaṁ pātubhāvo dullabho lokasmin”ti. Dutiyaṁ.

“Mendicants, the appearance of three individuals is rare in the world. What three? A Realized One, a perfected one, a fully awakened Buddha. A teacher of the teaching and training proclaimed by a Realized One. An individual who is grateful and thankful. The appearance of these three individuals is rare in the world.”
