An Arahant. He was the son of a nobleman in the Vajjī country, and having heard the Buddha teach the Ratana Sutta he left the world. One day, while striving after insight, he was caught in the rain and sought shelter in a woodman’s hut. As soon as he sat down there on a mat he became an Arahant. The Buddha, having heard by virtue of his divine ear the conversation between the monk and the watchman, uttered verses of approbation. The monk was so called because he obtained insight in a hut.

In the past he had given cool water to Padumuttara Buddha (Thag.v.56; ThagA.i.129 f).

He is probably identical with Udakapūjaka Thera of the Apadāna. Ap.i.142 f.
