Holi is a Hindu festival that the Indian diaspora has carried around the world. The first textual notation of the holiday dates from the seventh century and tells the mythic story of Pralhad, a devotee of the supreme god, Vishnu, but son of a demon. His father ordered him to sit on a bed of fire, and he survived unscathed. Thus, Holi marks the triumph of good over evil and the passing of winter and the coming of spring. Many traditions are associated with the holiday. The most common is the throwing of colored sand and water. The Asian Culture Center brought that tradition to Dunn Meadow this month and transformed the dull brown field of winter into a rainbow of colored sand.
