"The illustrious Bhrigu came out, ripping open the breast of Brahman. The learned Sukra is Bhrigu's son. And the learned Sukra becoming a planet and engaged according to the command of the Self-existent in pouring and withholding rain, and in dispensing and remitting calamities, traverses, for sustaining the lives of all the creatures in the three worlds, through the skies. And the learned Sukra, of great intelligence and wisdom, of rigid vows, leading the life of a Brahmacharin, divided himself in twain by power of asceticism, and became the spiritual guide of both the Daityas and the gods. And after Sukra was thus employed by Brahman in seeking the welfare (of the gods and the Asuras), Bhrigu begot another excellent son. This was Chyavana who was like the blazing sun, of virtuous soul, and of great fame. And he came out of his mother's womb in anger and became the cause of his mother's release, O king (from the hands of the Rakshasas). And Arushi, the daughter of Manu, became the wife of the wise Chyavana. And, on her was begotten Aurva of great reputation. And he came out, ripping open the thigh of Arushi. And Aurva begot Richika. And Richika even in his boyhood became possessed of great power and energy, and of every virtue. And Richika begot Jamadagni. And the high-souled Jamadagni had four sons. And the youngest of them all was Rama (Parasurama). And Rama was superior to all his brothers in the possession of good qualities. And he was skilful in all weapons, and became the slayer of the Kshatriyas. And he had his passions under complete control. And Aurva had a hundred sons with Jamadagni the eldest. And these hundred sons had offspring by thousands spread over this earth.
