Sāvatthinidānaṃ. Ekamantaṃ nisinno kho so bhikkhu bhagavantaṃ etadavoca: “ko nu kho, bhante, hetu, ko paccayo, yenekadā uṇhaṃ hotī”ti? “Santi, bhikkhu, uṇhavalāhakā nāma devā. Tesaṃ yadā evaṃ hoti: ‘yannūna mayaṃ sakāya ratiyā vaseyyāmā’ti, tesaṃ taṃ cetopaṇidhimanvāya uṇhaṃ hoti. Ayaṃ kho, bhikkhu, hetu, ayaṃ paccayo, yenekadā uṇhaṃ hotī”ti.
