“Everything an Indian does is in a circle, and that is because the power of the World always works in circles, and everything tries to be round . . . The sky is round and I have heard the earth is round like a ball, and so are all the stars. The wind in its greatest power whirls, birds make their nest in circles, for theirs is the same religion as ours. The sun comes forth and goes down again in a circle. The moon does the same and both are round. Even the seasons form a great circle in their changing, and always come back again to where they were. Our teepees were round like the nests of birds. And they were always set in a circle, the nation’s hoop.”
