Kāḷadīghavāpi untranslated

Kāḷadīghavāpi. A lake, evidently in Ceylon. Cūḷa Piṇḍapātikatissa saw an elephant’s corpse floating in the lake and made it his subject of meditation for Arahant-ship. Vsm.i.191.

There was evidently a vihāra attached to it. The Majjhima Commentary (Ma.i.353f) gives a story of a novice who lived there.
