Why Holi is  Celebrated -:There is a symbolic legend to explain why Holi is celebrated as a festival of colours. The word "Holi" originates from the word "Holika", she was the evil sister of the demon king Hiranyakashiyap.

King Hiranyakashipu, according to legend, was the King of  modern days Multan( now in Pakistan) and had earned a boon that made him virtually indestructible. He grew arrogant and  thought he is a God, and demanded that everyone should worship only him.
Hiranyakashipu's own son, Prahlada, however disagreed, to the opinion of his father the King. He was and remained devoted to Lord Vishnu ( The preserver of the Universe in Hindu religion).

This infuriated Hiranyakashipu, 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. Holika was blessed and immune to injury from fire, while Prahlada was not. As the fire flames took over  Holika and Prahlada, by the good will of Prahlad and the blessings of Lord Vishnu on him, the  Holika burned and  Prahlada survived.

Seeing this, Hiranyakashipu, unable to control his anger, smashed a pillar with his mace. There was a tumultuous sound, and Lord Vishnu appeared as Lord Narasimha ( half men and half Lion) and killed Hiranyakashipu. The bonfire is a reminder of the symbolic victory of good over evil, of Prahlada over Hiranyakashipu, and of the fire that burned Holika. The next day when the fire cooled down, people applied ash to their foreheads, a practice still observed by some people. Eventually, coloured powder came to be used to celebrate Holi.
Still traditionally Holi celebrations start on the night before the main festival Holi with a Holika bonfire where people gather, they pray and bonfire as a symbol of the victory of good over bad.
