Origin story At one time when the Buddha was staying at Sāvatthī in Anāthapiṇḍika’s Monastery, a government official called Ārohanta became a monk and his ex-wife a nun. On one occasion that monk was having his meal in the presence of that nun. While he was eating, she attended on him with drinking water and a fan, and she flirted with him. But he dismissed her, saying, “Don’t do that; it’s not allowable.” “Before you did such and such to me, but now you can’t even take this much.” And she dropped the water vessel on his head and struck him with the fan.
