n. voluntary, desired or curative possession by a spirit
In the sociology of religion, Luc de Heusch coined the term adorcism for practices to placate or accommodate spiritual entities in a possessed person or place. Unlike exorcism, the relationship with the entities is potentially positive. This is sometimes used as initiation into a spirit cult.
Jean-Michel Oughourlian defines adorcism as "voluntary, desired, and curative possessions".
