Once there was a king Hiranyakashipu and he had boon which made him indestructible. He wanted every one to worship him as God. However his son Prahlad refused it and he punished several times but he got saved somehow.
         One day Hiranyashipu’s sister – Holika used trick and asked Prahlad to sit on pyre with her. And she was wearing cloak which flew after a while and she got burnt but Prahlad was saved by Vishnu. Also Vishnu killed Hiranyashipu.
          This bonfire is the remainder symbolic of victory of good over evil. Henceforth, holi is started celebrating every year.
