The power of the world
always works in circles.
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 nests
in circles,
for theirs is the same religion as ours.
The sun
comes forth and goes down
in a circle
The moon does the same.
And both always come back
to where they were.
The life of man is a circle
from childhood to childhood.
And so it is in everything
where power moves.'
