4.2.p12

An ascetic, named Saubhari, versed in Rig Veda lived in the waters for twelve years. There lived a huge fish, who was the sovereign, named Sammada, He had a numerous progeny. His children and grand children used to sport around him in all directions and he lived happily amongst them, playing with them day night before the ascetic. Being disturbed in his devotions that ascetic, in the waters, beholding the sport of the king of fish with his children and grand children, thought within himself—"Blessed is the being, who, although born in a degraded state, is sporting with his children and grand children. This has created envy in me and I wish to sport with my children and grand children". Having thus made up his mind the ascetic speedily came up from the water and being desirous of becoming a householder went to Māndhāta to demand one of his daughters as his wife.
