The colourful Hindu festival of Holi is a celebration of good over evil. ‘Holi’ is derived from ‘Holika’, the name of an ancient demon king’s sister who treacherously helped the king plot the death of his son. However, the plan failed unexpectedly when she was burned by fire and Prahlad, the king’s son who was devoted to Lord Naarayana, escaped unscathed. Hindus commemorating this triumph light bonfires, burn effigies of Holika and relish dousing each other in vivid colours with joy and abandon.
