What is the connection between Mahabharata to Diwali?

Diwali, the Festival of Lights, is closely connected to the Mahabharata through the celebration of Lord Krishna's victory over the demon Narakasura, which is observed on the day of Naraka Chaturdashi, just before Diwali. Krishna's triumph symbolizes the victory of good over evil, paralleling the broader themes of the Mahabharata. Additionally, the festival marks the return of the Pandavas to their kingdom after 13 years of exile, celebrated with lights and joy, symbolizing hope and new beginnings.
