Prahlad accepted the challenge and prayed to Vishnu to keep him safe. When the fire started, everyone watched in amazement as Holika was burnt to death, while Prahlad survived without a scar to show for it. The burning of Holika is celebrated as Holi. According to some accounts, Holika begged Prahlad for forgiveness before her demise, and he decreed that she would be remembered every year at Holi.
