As per Hindu mythology, the demon king Hiranyakashyap who was blessed with power by the gods had started wreaking havoc on earth. The demonic leader tortures his people and had forced every human in his kingdom to start preaching to him as their lord. On the other hand, Hiranyakashyap's pious son was a faithful devotee of Lord Vishu. Even after multiple threats by Hiranyakashyap, his son Prahlad continued to worship Lord Vishnu.
