“Everything the power of the world does, is done in a circle. The sky is round, the earth is round like a ball, and so are all the stars. The wind, in its greatest power, whirls… the sun comes forth and goes down in a circle. The moon does the same… even the seasons form a great circle in their changing, and always come back again to where they were before. The life of a man is a circle… and it is in everything where power moves.” –Black Elk
