it is said that it is to celebrate the arrival of lord Ram in Ayodhaya after victory at lanka over Ravan.
But it appears that it is to save rice crop from insects as the lights burn them. whatever it is a joyous occasion
with lights, crackers and sweets.
Insects love the light also. Yet is not the soft glow of the spiritual lights they are atrracted to.
All your folklore and history is filled with such beautiful spiritual backgound prahatsinha. Perhaps one
day i will be apart of such celebrations.We are beginning to honor such traditions here in southern california
and in other parts of our country.
