I think I have told you, but if I have not, you must have understood, that a man who has a vision is not able to use the power of it until after he has performed the vision on earth for the people to see.
Black ElkCrazy Horse dreamed and went into the world where there is nothing but the spirits of things. That is the real world that is behind this one, and everything we see here is something like a shadow from that world.... It was this vision that gave him his great power, for when he went into a fight, he had only to think of that world to be in it again, so that he could go through anything and not be hurt
Black ElkEverything an Indian does is in a circle, and that is because the power of the world always works in circles.
