Jamadagni (Sanskrit: जमदग्नि, lit. 'great fire') is a sage in Hindu literature. He is regarded in Hindu tradition to be one of the Saptarishi (Seven Vedic sages) in the 7th, and the current age of Manvantara.
He is a descendant of the sage Bhrigu, one of the Prajapatis created by Brahma, the creator deity. Jamadagni has five children with his wife, Renuka, the youngest of whom is Parashurama, an avatar of Vishnu.
The Saptarshi (Sanskrit: सप्तर्षि, lit. 'Seven sages' IAST: Saptarṣi) are the seven seers of ancient India who are extolled in the Vedas, and other Hindu literature such as the Skanda Purana. The Vedic Samhitas never enumerate these rishis by name, although later Vedic texts such as the Brahmanas and Upanisads do, so these constellations are easily recognizable.
Parashurama (Sanskrit: परशुराम, romanized: Paraśurāma, lit. 'Rama with an axe'), also referred to as Rama Jamadagnya, Rama Bhargava and Virarama, is the sixth avatar among the Dashavatara of the preserver god Vishnu in Hinduism. Hindu tradition holds him to be the destroyer of evil on Earth. He liberates the Mother Earth from felons, ill-behaved men, extremists, demons and those blind with pride. He is described as one of the Chiranjivi (Immortals), who will appear at the end of the Kali Yuga to be the guru of Vishnu's tenth and last incarnation, Kalki.
Born to Jamadagni and Renuka, the Brahmin Parashurama was foretold to appear at a time when overwhelming evil prevailed on the earth. The Kshatriya caste, with weapons and power, had begun to abuse their power, take what belonged to others by force, and tyrannise people. He corrected the cosmic equilibrium by destroying these Kshatriyas twenty-one times (leaving some lineages). He is married to Dharani, an incarnation of Lakshmi, the wife of Vishnu.
Bhrigu (Sanskrit: भृगु, IAST: Bhṛgu) is a rishi in Hindu tradition. He is one of the seven great sages, the Saptarshis, and one of the many Prajapatis (the facilitators of creation) created by Brahma. He was the first compiler of predictive astrology and also the author of Bhrigu Samhita, an astrological (jyotisha) classic. Bhrigu is considered a manasaputra ("mind-born son") of Brahma. The adjectival form of the name, Bhārgava, is used to refer to the descendants and the school of Bhrigu. According to Manusmriti, Bhrigu was a compatriot and companion of Svāyambhuva Manu, the progenitor of humanity. Along with Manu, Bhrigu made important contributions to the Manusmṛti, which was constituted out of a sermon to a congregation of saints in the state of Brahmavarta, after the great floods in this area. As per the Skanda Purana, Bhrigu migrated to Bhrigukaccha, modern Bharuch, on the banks of the Narmada river in Gujarat, leaving his son Chyavana at Dhosi Hill.
According to Bhagavata Purana, he was married to Khyati, one of the nine daughters of Prajāpati Kardama. She was the mother of Lakshmi as Bhargavi. They also had two sons named Dhata and Vidhata. He had one more son with Kavyamata, 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 with Puloma, as is the folk hero Mrikanda. [Maha:1.5] One of his descendants was sage Jamadagni, who in turn was the father of sage Parashurama, considered an avatar of Vishnu.
