Festival of Deepawali celebrated across India by people of all religion symbolises victory of good over evil. As per mythology Lord Rama reached back Ayodhya (His Kingdom) on this day after completion of his 14 years exile and vanquishing Ravana in a bitter battle at Lanka.
This day happened to be a New moon day (No moon). Residents had lit up their houses with the help of earthen lamps to welcome the prince (Rama). People in the present day have started using electric lights along with earthen lamps to commemorate the occasion. People burst crackers too to express happiness.Deepawali remains associated with cleanliness and lights.
