Who Parashurama is
Parashurama is Rama with the axe, the sixth of the ten avatars of Vishnu, and the strangest of them: a brahmin, a priest's son, who lived as a warrior and killed kings.
He was the youngest son of the sage Jamadagni and his wife Renuka. His first famous deed was the hardest: at his father's command he struck off his mother's head with his axe, and then, offered any reward, asked for her to be brought back to life and to forget what he had done.
His great deed came after. The thousand-armed king Kartavirya Arjuna took his father's cow, and Parashurama killed him; the king's sons killed his father in revenge; and Parashurama took his axe against every warrior king on earth, twenty-one times over, the Bhagavata says. At the end of it he gave the whole earth away and went to live on Mount Mahendra.
Om Jamadagnyaya vidmahe, mahaviraya dhimahi, tanno Parashurama prachodayat: the Gayatri of Parashurama, son of Jamadagni, great hero.
Having given the earth away, he had nowhere of his own, and so, on the western coast of India, they say he threw his axe into the ocean and the sea drew back, leaving the land of Kerala.
Unlike the other avatars, he does not die. He is one of the chiranjivi, the long-lived ones, who will be on earth until the end of this age. He appears again and again in the epics, an old man now: he teaches Bhishma, Drona and Karna; he confronts Rama, his own next avatar, after the bow of Shiva is broken, and gives way to him; and in the Kalki Purana he will teach Kalki, the last avatar.
