An Indian man is fighting for the right to believe in the non-existence of God. But Ravi Kumar's quest for a document granting him legal recognition for his status has got him into trouble with the authorities. The BBC's Geeta Pandey reports from Tohana village in northern India. With two large tattoos that declare him to be an "atheist" covering his forearms, 33-year-old Ravi Kumar says he realised there was no God when he was just six or seven.
