Magic: History, Theory, and Practice is a mysticism book by Ernst Schertel originally published in Germany in 1923. Schertel identifies heavily with the “demonic” in Magic, espousing the belief that “communion with the demon” is the most important aspect of magical/religious practice. Schertel had sent a dedicated copy of the book to Adolf Hitler. Hitler read the book and marked several passages. A total of sixty-six annotations were made by Hitler in his copy.
