Parashurama in the context of "Jamadagni"

Treta Yuga (IAST: Tretā-yuga) (Devanagari: त्रेतायुग), in Hinduism, is the second and second-best of the four yugas (world ages) in a Yuga Cycle, preceded by Krita (Satya) Yuga and followed by Dvapara Yuga. Treta Yuga lasts for 1,296,000 years (3,600 divine years).

Treta means 'a collection of three things' in Sanskrit, and is so called because during the Treta Yuga, there were three Avatars of Vishnu that were seen: the fifth, sixth and seventh incarnations as Vamana, Parashurama and Rama, respectively. The bull of Dharma symbolizes that morality stood on three legs during this period. It had all four legs in the Satya Yuga and two in the succeeding Dvapara Yuga. Currently, in the immoral age of Kali, it stands on one leg.

The Dashavatara (Sanskrit: दशावतार, IAST: daśāvatāra) are the ten primary avatars of Vishnu, a principal Hindu god. Vishnu is said to descend in the form of an avatar to restore cosmic order. The word Dashavatara derives from daśa, meaning "ten", and avatāra, roughly equivalent to "incarnation".

The list of included avatars varies across sects and regions, particularly with respect to the inclusion of Balarama (brother of Krishna) or the Buddha. Though no list can be uncontroversially presented as standard, the "most accepted list found in Puranas and other texts is [...] Krishna, Buddha." Most draw from the following set of figures, in this order: Matsya, Kurma, Varaha, Narasimha, Vamana, Parashurama, Rama, Krishna, or Balarama, Buddha or Krishna, and Kalki. In traditions that omit Krishna, he often replaces Vishnu as the source of all avatars. Some traditions include a regional deity such as Vithoba or Jagannath in penultimate position, replacing Krishna or Buddha. All avatars have appeared except one: Kalki, who will appear at the end of the Kali Yuga.

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.

The Harivamsa (Sanskrit: हरिवंश, lit. 'The genealogy of Hari', IAST: Harivaṃśa) is an important work of Sanskrit literature, containing 16,374 shlokas, mostly in the anustubh metre. The text is also known as the Harivamsa Purana. This text is believed to be a khila (appendix or supplement) to the Mahabharata and is traditionally ascribed to Vyasa. The most celebrated commentary of the Mahabharata by Neelakantha Chaturdhara, the Bharata Bhava Deepa also covers the Harivamsa. According to a traditional version of the Mahabharata, the Harivamsa is divided into two parvas (books) and 12,000 verses. These are included with the eighteen parvas of the Mahabharata. The Critical Edition has three parvas and 5,965 verses.

The Adi Parva of Harivamsa describes the creation of the cosmos and the legendary history of the kings of the Solar and Lunar dynasties leading up to the birth of Krishna. Vishnu Parva recounts the history of Krishna up to the events prior to the Mahabharata. Bhavishya Parva, the third book, includes two alternate creation theories, hymns to Shiva and Vishnu and provides a description of the Kali Yuga. While the Harivamsa has been regarded as an important source of information on the origin of Vishnu's incarnation Krishna, there has been speculation as to whether this text was derived from an earlier text and what its relationship is to the Brahma Purana, another text that deals with the origins of Krishna.

Goddess Renuka or Mahur Renuka, also known as Renuka Bhavani, Yellamma Devi, is a Hindu mother goddess venerated predominantly in the South & Western Indian states of Karnataka, Tamil Nadu, Telangana, Andhra Pradesh, Gujarat, Maharashtra, Madhya Pradesh. She is regarded as the mother of Parashurama, the sixth avatar of the Vishnu and is considered a manifestation of the Mother Goddess or Shakti in regional devotional traditions in Hindu mythology.
