This story is part of the prelude to the Ramayana, and tells of the demon Rahwana. Rahwana disturbs the hero Arjunasahasrabahu when he is sporting with his wife in a river. The hero has transformed himself into his cosmic form in order to dam a river for his wife's ease. A battle with Rahwana follows, in which the demon king is imprisoned by the hero.
