Lighting up to celebrate the triumph of good over evil
And it is not called the Festival of Lights for nothing, for it is celebrated with a joyful vivacity, with bright lights and even brighter smiles, as though to underline the traditional meaning and message behind it. Even the word "Deepavali" is etymologically derived from the Sanskrit word that literally means "row of lights".
