Abbhavalāhakasutta

sn32.55:1.1 At Sāvatthī.

sn32.55:1.2 Seated to one side, that mendicant said to the Buddha:

sn32.55:1.3 “Sir, what is the cause, what is the reason why sometimes it becomes stormy?”

sn32.55:1.4 “Mendicant, there are what are called gods of the stormy thunderclouds.

sn32.55:1.5 Sometimes they think:

sn32.55:1.6 ‘Why don’t we revel in our own kind of enjoyment?’ Then, in accordance with their wish, it becomes stormy.

sn32.55:1.7 This is the cause, this is the reason why sometimes it becomes stormy.”
