Diwali is the festival of Laxmi, the Goddess of prosperity and wealth. It is believed that Goddess Laxmi visit everyone during Diwali and brings peace and prosperity to all. On the night of Diwali "Lakshmi-Pujan" is performed in the evenings. A traditional Pujan is performed after sunset in all the homes.
Five pieces of ghee diyas (lamps) are lit in front of the deities, naivedya of traditional sweets is offered to the Goddess and devotional songs are sung in praise of Goddess Laxmi. After Deepawali Puja people light diyas (lamps) in their homes to usher in light and clear the darkness from the world.
In villages cattle are adorned and worshipped by farmers as they form the main source of their income. In south, cows are offered special veneration as they are supposed to be the incarnation of Goddess Lakshmi and therefore they are adorned and worshipped on this day.
