Essentially they have forgotten their own needs and dedicate themselves to the Great Spirit. The great Sioux Chief, Crazy Horse, received most of his power through the lamenting ritual which he performed several times a year, including during the winter. Others who are also known to have sought visions were Black Elk, Ice of the Cheyennes, Plenty Coups of the Crow, Chief Joseph of the Nez Perce, Whirlwind Chaser and Elk Head of the Sioux. Visions were sought on lonely mountaintops. The higher the place, the closer it is to the Great Spirit.
Women go to a hill or valley because such are considered protected places.
Men go up to the mountains. This includes sweat baths, smudging with sage or pine needles, and other practices the guide may suggest. Then, the seeker must paint his or her body with white clay, bring a buffalo robe, pipe, and moccasins, and wear a breechcloth. Vision seeking continues from one to five days, four days being the ideal, during which neither food nor water is taken. The Sioux often set up a center post to which offerings are tied, and four other posts in the form of a cross with cloth flags tied to them.
