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".

Deepavali owes its origins to the epic stories narrated in the Hindu religious scriptures. Perhaps the most popular origin story is recounted in the Ramayana in which Lord Rama reunites with his wife Sita following a 14-year exile, and after having killed the demon king Ravana.

In the epic tale, the denizens of the kingdom of Ayodhya celebrated the prince's triumphant return to his homeland and later, his ascension to the throne, by lighting up their homes and the streets with earthen oil lamps. This happened on the night of the new moon and is commemorated hence, as the celebration of Deepavali. However, the story of Lord Rama's victory over Ravana is only one out of many that is said to have given rise to this annual celebration.

One other popular tale remembered during the occasion is that of the battle between Lord Krishna and the evil asura (demon) Narakasura. Krishna emerged victorious after a long and drawn-out struggle, and his victory was celebrated with the lighting of lamps. Yet others believe that Deepavali marks the day when the prideful and evil Mahishasura was vanquished at the hands of the goddess Kali.Variations notwithstanding, these stories share a common thread; that of the removal of evil, to be replaced by that which is good. This sense of renewal is reflected in the way Hindus prepare themselves for Deepavali.

In anticipation of the celebration, homes as well as their surrounding areas are cleaned from top to bottom; decorative designs such as the kolam are drawn or placed on floors and walls; and the glow of lights, whether emitted from the traditional vilakku (oil lamps fashioned out of clay) or colourful electric bulbs, brighten up the abode of both rich and poor, signalling the coming festivities.
