A cave in Kotlpabbata vihāra. A novice once recited there the Mahāsamaya Sutta, and a goddess, in the nāga tree outside, applauded him. She had been present when the Buddha preached the sutta when, she said, the concourse of devas was so great that she could get a foothold only in the sea near Mahagāma in Ceylon; yet she could see and hear the Buddha distinctly.
