Voodoo

In voodoo, the human spirit has two parts.

Gros Bon Ange is the Big Good Angel - the life force that all beings share and which animates them. This enters the body at conception and returns to God, to the point of origin, at death.

Ti Bon Ange is the Little Good Angel - this is the individual soul, one's essence, one karma - the sum of one's choices, actions and beliefs.

Voodoo black magic can capture a ti bon ange at the point of death.
It's thought a powerful magician can steal it from a living person.

A magus can take a corpse and install the ti bon into it, creating a cheval, a kind of zombie. The zombie is alive again, no longer a corpse, but animated by the stolen ti bon, not it's own. The ti bon yearns for heaven, but is under the control of the magus.
