Everything 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. In the old days when we were a strong and happy people, all our power came to us from the sacred hoop of the nation, and so long as the hoop was unbroken the people flourished.
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 ElkWe should understand well that all things are the work of the Great Spirit. We should know the Great Spirit is within all things: the trees, the grasses, the rivers, the mountains, and the four-legged and winged peoples; and even more important, we should understand that the Great Spirit is also above all these things and peoples. When we do understand all this deeply in our hearts, then we will fear, and love, and know the Great Spirit, and then we will be and act and live as the Spirit intends.
