"In The Sixth Grandfather, Dr. DeMallie reveals himself to be a uniquely sensitive interpreter of Lakota theology, philosophy, and history—which are all one in traditionalist Lakota thought. His editing is a masterpiece of scholarly skill and spiritual insight, insight that penetrates the inner beings of both Black Elk and John G. Neihardt, two men of vastly different cultures who became one as seekers of the Sacred. The Sixth Grandfather is, as it were, the completion of the holy task begun in Black Elk Speaks and When the Tree Flowered."— Father Peter J. Powell, author of People of the Sacred Mountain
"As a careful anthropological document or a moving personal testimony, the legacy here preserved deserves a wide readership."—Library Journal
