The god Parashuram, intending to throw back the sea, was prevented by the intervention of the Agri and Mangela women.
Bhishma and Karna, half brother of Pandava also took instruction in weaponry from Parashurama, a disciple of lord Shiva, and was known to have terrible temper having lost his father to the evil Asura.
Parashurama tried to wash the blood stains off the axe by dipping it in various rivers, but a sesame-sized blood stain remained on his axe, until he dipped his axe in the Tunga river near Thirthahalli.
Shiva stopped at a spot, now Thrissur, for his seat and later he and his party disappeared and Parashurama saw a bright and radiant Shiva linga at the foot of a huge banyan tree.
This resulted in Satyavati's mother giving birth to Vishvamitra, the son of a Kshatriya Gadhi with the qualities of a Brahmin; and Satyavati gave birth to Jamadagni, the father of Parashurama, a Brahmin with qualities of a Kshatriya.
