Traditional Diwali involves lighting of diyas or small clay lamps. These clay lamps are filled with oil then kept lit during the course of the night. The ritual signifies the conquest of good against evil, light versus darkness. The house is cleansed as a result of lighting diyas. To drive evil spirits away, firecrackers are lit during the festival.
