which important event in hinduism is marked by diwali?

Diwali, also known as the Festival of Lights, marks an important event in Hinduism: the return of Lord Rama to Ayodhya along with his wife Sita and brother Lakshmana after defeating the demon king Ravana. This event symbolizes the victory of good over evil, light over darkness, and knowledge over ignorance. People light earthen lamps (diyas) to celebrate this triumph and welcome Lord Rama back home. Additionally, in some regions, Diwali commemorates the victory of Lord Krishna over the demon Narakasura, reinforcing the theme of good conquering evil. The festival also honors the goddess Lakshmi, symbolizing wealth and prosperity, and involves various cultural, spiritual, and religious rituals over five days, marking the Hindu New Year.
