shaman is a tribal healer who can act as a medium between the visible world and the spirit world. Shamans are kind of a mix between priests and doctors. Like a priest, a shaman is a holy man who represents a religion — in this case, shamanism. Like a doctor, a shaman heals people — or at least claims to do so.

Shamanism is a type of religion that is led by a person called a shaman. The word shaman means “one who knows.” Shamans are both religious leaders and healers of the sick. In addition, they are believed to have special powers, such as the ability to tell the future. A shaman may be male or female.

Chaman – Un chaman est un guérisseur tribal qui peut agir comme un médium entre le monde visible et le monde des esprits. Les chamans sont une sorte de mélange entre les prêtres et les médecins. Comme un prêtre, un chaman est un homme saint qui représente une religion – dans ce cas, le chamanisme. Comme un médecin, un chaman guérit les gens – ou du moins prétend le faire.
