In this work, Dr. Carrington, one of the world's foremost psychic researches, brings his vast knowledge of scientific investigation to bear in editing the remarkable account of Sylvan Muldoon's 'out-of-the-body' experiences. Mr. Muldoon gives not only a vivid account of his own astral experiences, but instructions to the student in the technique of projecting the astral body. He makes no attempt to prove to sceptics the truth of the phenomena.
