Mother goddess
As per the Kalikula sect of Shaktism, the supreme celestial Mother goddess Mahakali took 10 manifestations to slay evils on the Earth, which are collectively known as Mahavidyas. Each Mahavidya has a day of incarnation in the Hindu calendar of 12 months. Out of those 10 Mahavidyas, the last goddess is Kamalatmika, whose day of incarnation is celebrated as Kamalatmika Jayanti, falls on the day of Deepavali. She is often recognized as 'Tantrik Lakshmi'. In the rest of Indian subcontinent, the day is associated with deity Rama or Krishna. Since both of them are central Gods of Vaishnavism, most Indians celebrate Deepavali as a Vaishnavite-oriented festival and thus worship Lakshmi, the consort of Mahavishnu as the supreme mother Goddess.
