Udāna 1.4

Huṃhuṅkasutta

Evaṃ me sutaṃ—​   ekaṃ samayaṃ bhagavā uruvelāyaṃ viharati najjā nerañjarāya tīre ajapā­la­nigrodhe paṭha­mā­bhisam­buddho. Tena kho pana samayena bhagavā sattāhaṃ ekapallaṅkena nisinno hoti vimutti­su­kha­paṭi­saṃ­vedī. Atha kho bhagavā tassa sattāhassa accayena tamhā samādhimhā vuṭṭhāsi.

Atha kho aññataro huṃhuṅkajātiko brāhmaṇo yena bhagavā tenupasaṅkami; upasaṅkamitvā bhagavatā saddhiṃ sammodi. Sammodanīyaṃ kathaṃ sāraṇīyaṃ vītisāretvā ekamantaṃ aṭṭhāsi. Ekamantaṃ ṭhito kho so brāhmaṇo bhagavantaṃ etadavoca: “kittāvatā nu kho, bho gotama, brāhmaṇo hoti, katame ca pana brāhmaṇakaraṇā dhammā”ti?

Atha kho bhagavā etamatthaṃ viditvā tāyaṃ velāyaṃ imaṃ udānaṃ udānesi: 

“Yo brāhmaṇo bāhita­pāpa­dhammo,
Nihuṃhuṅko nikkasāvo yatatto;
Vedantagū vūsitab­rahma­cariyo,
Dhammena so brahmavādaṃ vadeyya;
Yassussadā natthi kuhiñci loke”ti.

Catutthaṃ.
