Well. A shaman is some one who connects this world and the spirit world. In Shaman King, shamans team up with ghosts and spirits to achieve their goals. The greatest dreams of a shaman is to become the Shaman King, who is able to contact the Great Spirit (the spirit that every soul will eventually go back to) in order to be the savior of the world. Various magical and religious terms are spread through out the story but they merge into something explainable por the time the main plot arrives.
