Spring... Summer... Fall...

You have noticed that everything as 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
that 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....
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.
