Narasimha, the man lion, is counted as the fourth of Vishnu's ten principal avatars, the incarnations Vishnu takes at moments when the world's balance has tipped too far toward disorder. The story, told across the Puranas including a lengthy telling in the Bhagavata Purana, centers on the demon king Hiranyakashipu, who won from Brahma a boon making him unable to be killed by man or beast, by day or by night, indoors or outdoors, on the ground or in the air, or by any weapon, a set of conditions he believed made him effectively immortal. His own son Prahlada nonetheless remained devoted to Vishnu despite his father's persecution, and when Hiranyakashipu demanded to know where this god was, striking a palace pillar and asking whether Vishnu lived even there, Narasimha burst from the pillar itself. Neither fully man nor fully beast, he killed the demon at the threshold of the palace, neither indoors nor outdoors, at twilight, neither day nor night, across his own lap rather than the ground or the air, and with his claws rather than any weapon, satisfying every letter of the boon while defeating exactly what it had been designed to prevent. Artists across Indian temple sculpture and painting have rendered the killing itself in vivid detail for centuries, most commonly showing Narasimha seated with Hiranyakashipu laid across his lap and the demon's body torn open by his claws, an image meant less to dwell on violence for its own sake than to make the boon's every satisfied condition visible at a glance.
