The Hudson River along the island of Manhattan flows in either direction depending on the tide.
You have noticed that everything that 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....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.
