Narasingha, the lion: Vishnu according to which he would die neither by day nor at night, neither indoors or outdoors, and be killed by neither man nor beast. Considering himself invincible, he became a tyrant. In order to kill him, Vishnu assumed the form of a man-lion. He killed Hiranyakashipu at twilight on the threshold of his palace. But the demon’s son Prahalada was an ardent devotee of Vishnu and won his favor.
