NARASIMHA AVATAR

Narasimha is the half-lion and half-human avatar of Lord Vishnu. Vishnu took his fourth avatar to end the reign of the asura king Hiranya Kashyap and establish peace, order, and righteousness on earth.
Hiranya Kashyap (Hiranyakashipu) wanted to kill his own son Prahalad, a devotee of Vishnu. He had already tried multiple ways to kill him, but every attempt failed due to the power of devotion. He also lost his sister, Holika, in one of his failed attempts. Since Hiranyakashipu was blessed with boons by Lord Brahma, Vishnu waited for the right moment to take the half-human and half-lion avatar and kill him.
