Deepavali is a festival where people from all age groups participate. They give expression to their happiness by lighting earthen 'diyas' (lamps), decorating the houses, bursting firecrackers and inviting near and dear ones to their households for partaking in a sumptuous feast. The lighting of lamps is a way of paying obeisance to god for attainment of health, wealth, knowledge, peace, valor and fame.
It is one time in the whole year that children volunteer to leave their beds long before the day begins. In fact, the traditional oil bath at 3 a.m, is the only chore that stands between them and the pre-dawn adventures. They emerge, scrubbed clean to get into their festive attire, and light up little oil lamps, candles and scented sticks(agarbathis), the wherewithal for setting alight crackers and sparklers.
On Diwali night, little clay lamps are lit in Hindus homes, but now a days colored electric lamps are also used. What is the significance of lighting a lamp? There is a logical answer to this question. It is through the light that the beauty of this world is revealed or experienced. Most civilizations of the world recognize the importance of light as a gift of God. It has always been a symbol of whatever is positive in our world of experience.
To Hindus, darkness represents ignorance, and light is a metaphor for knowledge. Therefore, lighting a lamp symbolizes the destruction, through knowledge, of all negative forces- wickedness, violence, lust, anger, envy, greed, bigotry, fear, injustice, oppression and suffering, etc. Competition is stiff, and even the little girl in silk frocks and their finery are watching out for the best sparklers and flowerpots, the rockets and Vishnuchakras, which light-up the night sky like a thousand stars. Grown-ups are the soul of generosity. Festive bonhomie abounds.
