The protector and preserver of the universe- Lord Vishnu, is the God of gods. He restores the balance of this universe by helping the troubled and maintaining an equilibrium between good and evil.
The most aggressive incarnation of Lord Vishnu, Parshurama, was the son of Renuka and Jamadagni. And he was born on the 3rd day of Shukla Paksha of Vaisakh (the Hindu month).
Once, when Vana Parva, Kartavirya Arjuna, who was a legendary king of the Haihayas Kingdom of Madhya Pradesh, had put his head in the clouds and became pompous by trying to abuse his power.
Excellent at his skills, intelligent and aggressive at the same time, Parshuram had vowed to kill every Kshatriya existing on the planet, and he did so.
