One day you see a man walking down the road, the next day you come to his yard and find him dead... Why is it that he cannot do what the living do? It is because the thing that gave power to these parts is no longer there. That is the duppy, and that is the most powerful part of any man. Everybody has evil in them, and when a man is alive... he will not abandon himself to many evil things. But when the duppy leaves the body, it no longer has anything to restrain it and it will do more terrible things than any man ever dreamed of.- From 'Tell My Horse: Voodoo and Life in Haiti and Jamaica', Zora Neale Hurston, 1938
