When I got back to my father and mother and was sitting up there in our tepee, my face was still all puffed and my legs and arms were badly swollen; but I felt good all over and wanted to get right up and run around.

I was standing on the highest mountain of them all, and round about beneath me was the whole hoop of the world. And while I stood there I saw more than I can tell and I understood more than I saw; for I was seeing in a sacred manner the shapes of all things in the spirit, and the shape of all shapes as they must live together like one being. And I saw that the sacred hoop of my people was one of many hoops that made one circle, wide as daylight and as starlight, and in the center grew one mighty flowering tree to shelter all children of one mother and one father. And I saw that it was holy.
