Vodou anthropology gives a person multiple souls. The gwo bonanj, big good angel, is the animating self and the seat of consciousness; the ti bonanj, little good angel, is closer to conscience or the individual spark. Possession works by the gwo bonanj being displaced so the lwa can occupy the body — which is the explanation for why the horse retains no memory. At death the desounen ceremony separates the gwo bonanj from the corpse. It then spends a year and a day in the waters of Ginen before being retrieved and installed in a govi jar in a further ceremony. This is also the machinery behind the zonbi: a person whose gwo bonanj has been captured and detained leaves a body that can be directed. The multiplicity is inherited from West African soul-concepts and it makes the Haitian understanding of what happens at death considerably more procedural than the Christian one alongside which it operates.
