The Circle

"Everything the Power of the World does is done in a circle.
The sky is round and I 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
and always come back again to where they were.
The life of a man is a circle from childhood to childhood.
And so it is in everything where power moves."
Black Elk 1863-1950.
