Ranchi, India (October 17, 2013): Over 15 districts spread across Uttar Pradesh, Bihar, Jharkhand, West Bengal and Orissa saw Durga Puja with a difference this festival season. Instead of the goddess slaying Mahishasur, the usual story of the Puja, this year, tribals and people belonging to Scheduled Castes and backward classes in these districts are celebrating the "demon king" as a non-Aryan inhabitant and a just king of the land, with Durga representing Aryan invaders.
