This is an erudite work on the body and its various organs from the occultist's viewpoint.
The author being from an older generation, the book is immaculately well written.
The esoteric material is derived from the works of alchemists/occultists/cabalists etc.,including Parecelsus, Vesalius (the father of modern anatomy)and Robert Fludd, from the Middle Ages or perhaps older as well as from ancient Hindu texts. I found this material extremely dry and difficult to comprehend. (I ordered the book from the library only because I was interested in the chapter on the pineal gland, but then was tempted to read the whole book).
You would need to be an expert on such ancient occult matters, or keenly interested in the subject, to find the book at all readable.
One interesting point that attracted my attention, however, was that original man was reportedly androgynous and that the separation of the sexes took place in "the secondary or further course of tribal history". This fits in with revelations by Shirley Maclaine in her book "Camino" about a significant past life of hers in Atlantis.
Also of interest was the information that reptiles originally had a seeing eye at the back of their head (according to the author this can be confirmed in any geological museum) - in humans this hole has "boned over, and the eye has shrunk up into the so-called pineal gland".
The book includes many drawings and illustrations, but no photos.
To sum up, this book can be described as an overly erudite work on occultist views of the body, and as such will be of little interest to the average reader. Those with a real interest in the subject, however, may find the book fascinating.
