4. Nara-sinha, or Nri-sinha. ‘The man-lion.’ Vishnu assumed this form to deliver the world from the tyranny of Hiranya-kasipu, a demon who, by the favour of Brahmā, had become invulnerable, and was secure from gods, men, and animals. This demon’s son, named Prahlāda, worshipped Vishnu, which so incensed his father that he tried to kill him, but his efforts were all in vain. Contending with his son as to the omnipotence and omnipresence of Vishnu, Hiranya-kasipu demanded to know if Vishnu was present in a stone pillar of the hall, and struck it violently. To avenge Prahlāda, and to vindicate his own offended majesty, Vishnu came forth from the pillar as the Nara-sinha, half-man and half-lion, and tore the arrogant Daitya king to pieces.
