Lakshmi Puja is celebrated in the month of September or October during Diwali festival mostly in North and Eastern India.
Lakshmi is the Goddess of wealth, health, peace, prosperity and love. People clean and decorate their houses on the occasion as it is believed that Goddess Lakshmi will go to only clean houses and bless them with wealth and prosperity. People offer vermilion, turmeric and flowers to the idol. Goddess Lakshmi and Lord Ganesha are worshipped together at most places as it is considered fortunate and wisdom and wealth come together. In the night lamps are lightened to welcome the goddess.
