Yuvanāśva married one hundred wives, but he had no sons, and therefore he entered the forest. In the forest, the sages performed a sacrifice known as Indra-yajña on his behalf. Once, however, the King became so thirsty in the forest that he drank the water kept for performing yajña. Consequently, after some time, a son came forth from the right side of his abdomen. The son, who was very beautiful, was crying to drink breast milk, and Indra gave the child his index finger to suck. Thus the son became known as Māndhātā. In due course of time, Yuvanāśva achieved perfection by performing austerities.
Thereafter, Māndhātā became the emperor and ruled the earth, which consists of seven islands. Thieves and rogues were very much afraid of this powerful king, and therefore the king was known as Trasaddasyu, meaning "one who is very fearful to rogues and thieves." Māndhātā begot sons in the womb of his wife, Bindumatī. These sons were Purukutsa, Ambarīṣa and Mucukunda. These three sons had fifty sisters, all of whom became wives of the great sage known as Saubhari.
