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to students of various esoteric traditions because the notes and excerpts are taken from private and previously unpublished sources, and from authors whose outofprint books are not readily accessible.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