In the Sioux way of life, Wakan Tanka (Standard Lakota Orthography: Wakȟáŋ Tȟáŋka) is the term for "the sacred" or "the divine". This is usually translated as "The Great Spirit". However, according to Russell Means, its meaning is closer to "Great Mystery" as Lakota spirituality is not henotheistic. Before their attempted conversion to Christianity, the Sioux used Wakȟáŋ Tȟáŋka to refer to an organization of sacred entities whose ways were mysterious: thus, "The Great Mystery".
It is interpreted as the power or the sacredness that resides in everything, resembling some animistic and pantheistic beliefs. This term describes every creature and object as wakȟáŋ ("holy") or having aspects that are wakȟáŋ.
Wakan Tanka was supposed to have placed the stones and minerals in the ground; Also, supposed to change the seasons and weather, and plants were supposed to have come out of the ground by hands.
