The movement of the waves, of winds, of the earth is ever in the same lasting harmony. We do not stand on the beach and inquire of the ocean what was its movement of the past and what will be its movement of the future. We realize that the movement peculiar to its nature is eternal to its nature. The dancer of the future will be one whose body and soul have grown so harmoniously together that the natural language of that soul will have become the movement of the body.
