As per Hindu legend, a demon king named Hiranyakasipu was troubling the Devas (celestial deities). He obtained limitless powers from Brahma, that no human could kill him, nor could he be killed in morning, noon or night, nor in air, water or ground. Contrastingly, his son Prahlada was an ardent devotee of Vishnu, whom his father hated. Hiranyakasipu tried to kill Prahalada numerous times, just for him to be saved by the divine grace of Vishnu.
