In
Lakota tradition, Skan is the Motion of the universe, the lifeblood pulse of the body and the solar winds. The Great Spirit,
Wakan Tanka, reflected upon himself and created the four Superior Spirits, Wi (the first to be created, bringing light to the world), Skan, Maka (Mother Earth) and Inyan (the solid support of the Earth or the rock associated with the natural forces of the Earth).
