A certain layman of Sāvatthi bathed in the Aciravatī, and on his return, seeing the Buddha, invited him to a meal. The Buddha accepted and was waited on with great devotion. As a result the layman was born in Tāvatimsa, in a palace which came to be called Karanīyavimāna.
A further story is told similar to the above, except that the person fed is a monk and not the Buddha (Vv.55; VvA.248f).
