Sambahulabhikkhusutta
Atha kho sambahulā bhikkhū yena bhagavā tenupasaṅkamiṁsu …pe… ekamantaṁ nisinnā kho te bhikkhū bhagavantaṁ etadavocuṁ: “idha no, bhante, aññatitthiyā paribbājakā amhe evaṁ pucchanti: ‘kimatthiyaṁ, āvuso, samaṇe gotame brahmacariyaṁ vussatī’ti? Evaṁ puṭṭhā mayaṁ, bhante, tesaṁ aññatitthiyānaṁ paribbājakānaṁ evaṁ byākaroma: ‘dukkhassa kho, āvuso, pariññatthaṁ bhagavati brahmacariyaṁ vussatī’ti. Kacci mayaṁ, bhante, evaṁ puṭṭhā evaṁ byākaramānā vuttavādino ceva bhagavato homa, na ca bhagavantaṁ abhūtena abbhācikkhāma, dhammassa cānudhammaṁ byākaroma, na ca koci sahadhammiko vādānuvādo gārayhaṁ ṭhānaṁ āgacchatī”ti?
Several Mendicants
Then several mendicants went up to the Buddha … and asked him, “Sir, sometimes wanderers of other religions ask us: ‘Reverends, what’s the goal of leading the spiritual life under the ascetic Gotama?’ We answer them like this: ‘The goal of leading the spiritual life under the Buddha is to completely understand suffering.’ Answering this way, we trust that we repeat what the Buddha has said, and don’t misrepresent him with an untruth. We trust our explanation is in line with the teaching, and that there are no legitimate grounds for rebuttal or criticism.”
