3Perhaps the most philosophically mature of the great archetypal symbols is the Circle, together with its most frequent imagistic concretion the Wheel. From earliest recorded times the circle has been widely recognized as the most perfect of figures, both because of its simple formal perfection and for the reason stated in Heraclitus' apho- rism, "In the circle the beginning and the end are the same.".

6You 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 tries to be round Everything the Power of the World does is done in a circle. The sky is round, and 1 have heard that the earth is round like a ball, and so are all the stars. The wind, in its greatest power, whirls. Birds make their nests 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. Our tepees were rounds 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 out children.".
