In Native American mythology, Wakan Tanka (great mystery) is the supreme being and creator of the Lakota Sioux. Sometimes called Great Spirit, he is similar to the supreme beings found in the myths of many other North American peoples.
According to Lakota myth, before creation Wakan Tanka existed in a great emptiness called Han (darkness). Feeling lonely, he decided to create companions for himself. First, Great Spirit focused his energy into a powerful force to form Inyan (rock), the first god. Next, he used Inyan to create Maka (earth) and then mated with that god to produce Skan (sky). Skan brought forth Wi (the sun) from Inyan, Maka, and himself. These four gods were separate and powerful, but they were all part of Wakan Tanka.
The first four gods produced four companions—Moon, Wind, Falling Star, and Thunderbird—to help with the process of creation. In turn, these companions created various gods and spirits, including Whirlwind, Four Winds, Buffalo, Two-Legged Creatures (humans and bears), Sicun (thought), Nagi (spirit of death), Niya (breath of life), and Nagila (shadow). All of these beings were aspects of Wakan Tanka. Together, they created and oversee everything that exists.
