The Bodhisatta was once a sea spirit, and heard a water crow flying about, trying to check shoals of fish and flocks of birds, saying, "Don't drink too much sea water, be careful of emptying the sea." The sea spirit, seeing his greediness, assumed a terrible shape and frightened him away.
The story was related in reference to the great greediness of Upananda the Sákyan (q.v.). He is identified with the water crow. J.ii.441f.
