1At Sāvatthī … . Sitting to one side, that bhikkhu said to the Blessed One: "Venerable sir, what is the cause and reason why it sometimes becomes cool?"

"There are, bhikkhu, what are called cool-cloud devas. When it occurs to them, ‘Let us revel in our own kind of delight,’ [n.293] I follow Se and Ee: Yaṁ nūna mayaṁ sakāya ratiyā rameyyāma. Be reads the verb as vaseyyāma. Spk explains that cool weather during the rainy season or winter is a natural coolness caused by the change of seasons, but when it becomes extremely cold during the cool season, or cold during the summer, that is caused by the power of these devas. Similar explanations are given for the other cases. then, in accordance with their wish, it becomes cool. This, bhikkhu, is the cause and reason why it sometimes becomes cool."

1Sāvatthinidānaṁ. Ekamantaṁ nisinno kho so bhikkhu bhagavantaṁ etadavoca: "ko nu kho, bhante, hetu, ko paccayo, yenekadā sītaṁ hotī"ti?

"Santi, bhikkhu, sītavalāhakā nāma devā. Tesaṁ yadā evaṁ hoti: ‘yannūna mayaṁ sakāya ratiyā vaseyyāmā’ti, tesaṁ taṁ cetopaṇidhimanvāya sītaṁ hoti. Ayaṁ kho, bhikkhu, hetu, ayaṁ paccayo, yenekadā sītaṁ hotī"ti.

Tepaññāsamaṁ.
