This it??
The Sun Dance was the most spectacular and important religious ceremony of the Plains Indians of 19th-century North America. Ordinarily held by each tribe once a year usually at the time of the Summer Solstice. The Sun Dance last from four to eight days starting at the sunset of the final day of preparation and ending at sunset. It showed a continuity between life and death - a regeneration. It shows that there is no true end to life, but a cycle of symbolic and true deaths and rebirths. All of nature is intertwined and dependent on one another. This gives an equal ground to everything on the earth. "Powerful animals exhibit both physical and spiritual powers, just as the medicine man and shaman do, and as do the grains of tobacco in the sacred pipe. However, just like the rest of nature, humans must give of themselves to help keep the cycles of regeneration.
The Native American tribes who practiced this dance were: The Arapaho, Arikara, Asbinboine, Cheyenne, Crow, Gros, Ventre, Hidutsa, Sioux, Plains Cree, Plains Ojibway, Sarasi, Omaha, Ponca, Ute, Shoshone, Kiowa, and Blackfoot tribes. Their rituals varied from tribe to tribe.
