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. You remember that my great vision came to me when I was only nine years old, and you have seen that I was not much good for anything until after I had performed the horse dance near the mouth of the Tongue River during my eighteenth summer. And if the great fear had not come upon me, as it did, and forced me to do my duty, I might have been less good to the people than some man who had never dreamed at all, even with the memory of so great a vision in me. But the fear came, and if I had not obeyed it, I am sure it would have killed me in a little while.
It was even then only after the heyoka ceremony, in which I performed my dog vision, that I had the power to practice as a medicine man, curing sick people; and many I cured with the power that came through me. Of course it was not I who cured. It was the power from the outer world, and the visions and ceremonies had only made me like a hole through which the power could come to the two-leggeds. If I thought that I was doing it myself, the hole would close up and no power could come through. Then everything I could do would be foolish. There were other parts of my great vision that I still had to perform before I could use the power that was in those parts. If you think about my great vision again, you will remember how the red man turned into a bison and rolled, and that the people found the good red road after that. If you will read again what is written, you will see how it was.1
