Conversant with the truth in respect of everything, the Grandsire then took Kavi as his own son. Engaged in procreating creatures for peopling the earth, Bhrigu who is regarded as a Prajapati thence came to be called as Varuna's offspring. Endued with every prosperity, Angiras came to be called the offspring of Agni, and the celebrated Kavi came to be known as the child of Brahman himself. Bhrigu and Angiras who had sprung from the flame and the charcoals of Agni respectively, became the procreators of extensive races and tribes in the world. Verily, these three, viz., Bhrigu and Angiras and Kavi, regarded as Prajapati, are the progenitors of many races and tribes. All are the children of these three. Know this, O puissant hero. Bhrigu begot seven sorts all of whom became equal to him in merits and accomplishments. Their names are Chyavana, Vajrasirsha, Suchi, Urva, Sukra, that giver of boons, Vibhu, and Savana. These are the seven. They are children of Bhrigu and are hence Bhargavas. They are also called Varunas in consequence of their ancestor Bhrigu having been adopted by Mahadeva in the form of Varuna. Thou belongest to the race of Bhrigu. Angiras begot eight sons. They also are known as Varunas. Their names are Vrihaspati, Utathya, Payasya, Santi, Dhira, Virupa, Samvarta, and Sudhan was the eighth. These eight are regarded also as the offspring of Agni. Freed from every evil, they are devoted to knowledge only.
