Upon seeing Urvaśī, the celestial society girl, both Mitra and Varuṇa discharged semen, which they preserved in an earthen pot. The two sons Agastya and Vasiṣṭha later appeared from that pot, and they are therefore the common sons of Mitra and Varuṇa. Mitra begot three sons in the womb of his wife, whose name was Revatī. Their names were Utsarga, Ariṣṭa and Pippala.
