Laxmi Puja, or the worship of the goddess of prosperity and wealth, is the main event on Diwali in North and West India. It is believed that Goddess Laxmi visit everyone during Diwali and brings peace and prosperity to all.

It is extremely important to keep the house spotlessly clean and pure on Diwali. Goddess Lakshmi likes cleanliness, and she will visit the cleanest house first. This is also the reason why the broom is worshipped on this day with offerings of haldi and kumkum (turmeric and vermilion). Lamps are lit in the evening to welcome the goddess. They are believed to light up Her path.
