"You have noticed that everything an Indian does is in a circle, and that is because the Power of the World always works in circles, and everything and everything tries to be round.
The life of a man is a circle from childhood to childhood, and so it is in everything where power moves. Our teepees were round like the nests of birds, and these were always set in a circle, the nation's hoop, a nest of many nests, where the Great Spirit meant for us to hatch our children."
~ Black Elk, Oglala Sioux 1863-1950
