This is a new release of the original 1924 edition.

This book is incredibly valuable to students of various esoteric traditions because the notes and excerpts are taken from private and previously unpublished sources, and from authors whose out-of-print books are not readily accessible. Interesting information has been collected and annotated concerning such topics as blood telegraphy, ever-burning lamps, optics, spiritual skills in healing, transplantation, apparent death, isopathy, and magnetism. Includes a look into a Rosicrucian workshop.
