Vanṇabrāhmaṇa eloped, one day, with Bimbasena, King Brahmadatta's daughter, and took her away on his flying hamsa. During their flight, Vannabrāhmaṇa was stranded on an island while Bimbasena, left alone in the jungle, gave birth to a boy. The child was found and adopted by the king of Käsi. Bimbasena walked all the way to Kasi and took refuge with the keeper of the parc. Only after many years had passed, could Vannabrāhmaṇa be reunited with his family.
