It was a November afternoon last year. A crowd of about 1,000 people had gathered at Panchmah village in Gaya district of South Bihar, 30 km from Jharkhand border and surrounded by mountains.
A few villagers knocked the door of 45-year-old Arjun Das, a labourer and Mahadalit by caste. They asked him to accompany his wife, Rita Devi, 42, to the panchayat (village council).
