The mogat (also mokat) are the ghosts of the dead and the principal supernatural agents of Grand Valley Dani religion. They linger near the living, are held responsible for sickness, misfortune and death, and must be conciliated through the sacrifice of pigs, the cremation of the corpse, and the long sequence of mortuary exchanges that follow a death. The Dani recognise no creator high-god; ritual life centres instead on managing and deflecting the anger of the mogat. Sources differ on how sharply the ghost of a particular named dead person is distinguished from the collective host of the ancestral dead, the Dani emphasis falling on the practical work of appeasement rather than on individuating the dead.
