Parashurama is the sixth avatar of Vishnu in Hinduism. Born as a brahmin, Parshuram carried traits of a Kshatriya and is often regarded as a Brahmin-Kshatriya. He carried a number of Kshatriya traits, which included aggression, warfare and valor. Like other incarnations of Vishnu, he was foretold to appear at a time when overwhelming evil prevailed on earth.
The Kshatriyas class, with weapons and power, had begun to abuse their power, take what belonged to others by force and tyrannize people. Parashurama corrects the cosmic equilibrium by destroying these evil Kshatriya warriors.
According to Hindu mythologies, Parashurama was the son of sage Jamadagni and his wife Renuka, living in a hut. They have a celestial cow called Surabhi which gives all they desire (such a cow is known as kamdhenu) .A king named Arjuna Kartavirya learns about it and wants it. He asks Jamadagni to give it to him, but the sage refuses. While Parashurama is away from the hut, the king takes it by force.
Parashurama learns about this crime, and is upset. With his axe in his hand, he challenges the king to battle. They fight, and Parushama kills the king.
The warrior class challenges him, and he kills all his challengers. The legend, states James Lochtefeld, likely has roots in the ancient conflict between the Brahmin caste with religious duties and the Kshatriya caste with warrior and enforcement role.
In some versions of the legend, after his martial exploits, Parashurama returns to his sage father with the Surabhi cow and tells him about the battles he had to fight. The sage does not congratulate Parashurama, but reprimands him stating that a Brahmin should never kill a king. He asks him to expiate his sin by going on pilgrimage. After Parashurama returns from pilgrimage, he is told that while was away, his father was killed by warriors seeking revenge. Parashurama again picks up his axe and kills many warriors in retaliation. In the end, he relinquishes his weapons and takes up yoga
In other versions it is also said that Parshuram showed unquestionable loyalty towards his father and on his order he even cut off his mother Renuka's head. The sage pleased with his loyalty granted him a boon in which he asked him to restore his mother's life.
