There is a symbolic legend to explain why holi is well celebrated as a colour fest. The word "Holi" originates from "Holika", the evil sister of demon king Hiranyakashipu. King Hiranyakashipu had earned a boon that made him virtually indestructible. The special powers blinded him, he grew arrogant, thought he was God, and demanded that everyone worshiped only him.[1]
Hiranyakashipu's own son, Prahlada,[14] however, disagreed. He was and remained devoted to Vishnu.[11] This infuriated Hiranyakashipu. He subjected Prahlada to cruel punishments, none of which affected the boy or his resolve to do what he thought was right. Finally, Holika - Prahlada's evil aunt - tricked him into sitting on a pyre with her.[1] Holika was wearing a cloak (shawl) that made her immune to injury from fire, while Prahlada was not. As the fire roared, the cloak flew from Holika and encased Prahlada.[11] Holika burned, Prahlada survived. Vishnu appeared and killed Hiranyakashipu. The bonfire is a reminder of the symbolic victory of good over evil, of Prahlada over Hiranyakashipu, of fire that burned Holika.[12] The day after Holika bonfire is celebrated as Holi.
In Braj region of India, where Krishna grew up, the festival is celebrated for 16 days (until Rangpanchmi) in commemoration of the divine love of Radha for Krishna, a Hindu deity. The festivities officially usher in spring, with Holi celebrated as festival of love.[15] There is a symbolic myth behind commemorating Krishna as well. Baby Krishna transitioned into his characteristic dark blue skin colour because a she demon Putana poisoned him with her breast milk.[16] In his youth, Krishna despairs whether fair skinned Radha and other Gopikas (girls) will like him because of his skin colour. His mother, tired of the desperation, asks him to approach Radha and colour her face in any colour he wanted. This he does, and Radha and Krishna became a couple. The playful colouring of the face of Radha has henceforth been commemorated as Holi.[17][18] Beyond India, these legends to explain the significance of Holi (Phagwah) are common in some Caribbean and South American communities of Indian origin such as Guyana and Trinidad and Tobago.[19][20]
Holi festival has other cultural significance. It is the festive day to end and rid oneself of past errors, end conflicts by meeting others, a day to forget and forgive. People pay or forgive debts, as well as deal anew with those in their lives. Holi also marks the start of spring, and for many the start of new year.
