Diwali is celebrated across India with a rich variety of customs that differ from region to region, yet share common themes such as decorating homes, lighting lamps (diyas), exchanging gifts, and enjoying festive meals. In West Bengal, the festival is observed as Kali Puja, devoted to the goddess Kali. In Tamil Nadu, families create elaborate kolam patterns, while in Goa, Diwali commemorates the defeat of the demon Narkasur.
