Black Elk of the Sioux has been recognized as one of the truly remarkable men of his time in the matter of religious belief and practice. Shortly before his death in August, 1950, when he was the "keeper of the sacred pipe," he said, "It is my prayer that, through our sacred pipe, and through this book in which I shall explain what our pipe really is, peace may come to those peoples who can understand, and understanding which must be of the heart and not of the head alone. Then they will realize that we Indians know the One true God, and that we pray to Him continually."
