Maharishi Bhrigu (Sanskrit: Bhṛgu) was one of the seven great sages, the Saptarshis, one of the many Prajapatis (the facilitators of Creation) created by Brahma (The God of Creation), the first compiler of predictive astrology, and also the author of Bhrigu Samhita, the astrological (Jyotish) classic. Bhrigu is considered as a Manasa Putra (mind-born-son) of Brahma. The adjectival form of the name, Bhargava, is used to refer to the descendants and the school of Bhrigu.
Bhrigu was a compatriot of and lived during the time of Manu, the Hindu progenitor of humanity. Bhrigu had his Ashram (Hermitage) on the Vadhusar River, a tributary of the Drishadwati River near Dhosi Hill in the Vedic state of Brahmavarta, presently on the border of Haryana and Rajasthan in India. Along with Manu, Bhrigu made important contributions to 'Manusmriti', which was constituted out of a sermon to a congregation of saints in the state of Brahmavarta, after the great floods in this area, nearly 10,000 years ago. As per Skanda Purana, Bhrigu migrated to Bhrugukucch Bharuch on the banks of Narmada river in Gujarat, leaving his senile son Chyavana at Dhosi Hill. The later date archaeological findings at Bhrigu Kutch are dated 8500 years old.[relevant?– discuss]
He was married to Khyati, the daughter of Daksha. He had two sons by her, named Dhata and Vidhata. His daughter Sri or Bhargavi, married Vishnu (Narayana).
He has one more son through Kavyamata (Usana), who is better known than Bhrigu himself – Shukra, learned sage and guru of the asuras. The sage Chyavana is also said to be his son through Puloma. [Maha:1.5]
Bhrigu finds mention in Shiva Purana and Vayu Purana, where he is shown present during the great Yagna of DakshaPrajapati (his father-in-law). He supports the continuation of the Yagna of Daksha even after being warned that without an offering for Shiva, it was asking for a catastrophe for everyone present there.
