I'm not sure why it's "by" John G. Neihardt when it is an edited transcription of the words of Black Elk himself. However, it's a wonderful read. There's a more direct translation around, but this is the one I've read so far. The version I read has notations by Native American scholar Raymond J. DeMallie, which is helpful and insightful towards weeding out Neihardt's alterations of Black Elk's profound story and message. I love this book as a testament of faith and it is awesome as a text of survival in the midst of the attempted genocide of the Sioux by the United States. Most of all I am inspired by the spirituality of Black Elk.
