Deepawali or Diwali is certainly the biggest an the brightest of all Hindu festivals. It's the festival of lights (deep = light and avali = a row i.e., a row of lights) that's marked by four days of celebration, which literally illumines the country with its brilliance, and dazzles all with its joy. Each of the four days in the festival of Diwali is separated by a different tradition, but what remains true and constant is the celebration of life, its enjoyment and goodness.
