Lakshmi Puja on Diwali is an integral part of the Diwali celebrations. This day is also known by the name of 'Chopada-Puja'. Lakshmi-Puja is performed for the sole purpose of propitiating Goddess Lakshmi and to thank Her for the bestowal of her blessings on the humans. Lakshmi-Puja falls on the darkest night of Amavasya, though with the help of innumerable lamps and diyas this darkness is reduced to such an extent that it seems as if one is celebrating Diwali in broad daylight.

Lakshmi Puja on Diwali is a major part of the Diwali celebration in North and West India.
