Diwali is biggest and the brightest of all Hindu festivals, which illumines everyone with its brilliance and joy. According to Ramayana, when Lord Ram returned to Ayodhya after killing the Demon King Ravana, the citizens of Ayodhya lightened the entire city with diyas. So, each year people celebrate Diwali to honor the return of Rama with his wife Sita and brother Lakshmana to their hometown.
