To find a book amongst the plethora of magical texts, which details the proper usage of one of the most often cited grimoires is a rare thing indeed. Fascinating and informative, the author stays diligently within the confines of the grimoire, without divergence, which is so often the case with others.This remarkable book is essential for any individual wishing to persue traditional grimoiric work.

This book (and the work that it describes) stands on its own without rivals.

I know of no other publication that details both the specifics of the Goetic procedure and its results.
While there a number of editions of the Lemegeton ms and even a few modern variations on the technique (e.g. Carroll Runyon's and Lon Milo Duquette's systems), they do not provide the extensive accounts of actual experiences.

Each conjuration account provides the name and pronunciation of the spirit (as given by the spirit itself), its appearance as seen in physical form (not 'astral' vision or imagination), and the explanation of its powers. While the scholars and the thrill seekers may find these bits of information entertaining, to the practitioner they offer help that is not available anywhere else. Further, the results of these workings show that the powers ascribed to these spirits do not come from within the mind of the conjurer (a line made popular ever since Crowley's publication of Goetia) and are indeed more than just psychological forces.

In summary, this work is nothing short of revolutionary in the field of practical ceremonial magic. While the would-be practitioner still needs to obtain a copy of Lemegeton if he/she wishes to carry out similar experiments, I believe this text may well become a benchmark for all future Goetic workings.

The only work similair to this I have read is Steve Savedow's Goetic Workbook, at least stylistically. Content is another matter. Here appears to be the only printed material of someone following a grimoire exactly by the book and the results of it. Notice, I say a record of someones actual workings, journal entries and recollections of what they have actually done and not of vague claims about their extensive experience with magic.

I can’t find any reason to doubt the veracity of the author, and no one has been able to give any good reason to yet that I have read. It’s also clear the negative reviewers have not bothered to actually read the book so that’s all that needs to be said there.

As I've seen it explained before, the grimoires can be seen as lab manuals which contain the directions for the practice and use of magic. This work then can be seen as a report on said lab manual and the results of its application. Every single last author who claims to practice magic according to the grimoires ALWAYS adds or subtracts something; Aaron Leitch, Steve Savedow, and Joseph Lisiewski all changed something or added something to their work with the grimoires. There really isn’t anything else like this out there in which someone actually followed the grimoires to the dot -not more or less- and then reported their results, which I find reason enough to make it worth reading.

I'll just say it's a valuable book for anyone looking to eventually take up this system in its entirety. If not for the initial opinions from a practitioner & a fairly detailed ritual outline, then for the clarification of several obscure words, names & practices of the Goetia. All of the evocations also provide insight into the art as well as plain ol' entertainment. I'm trying not to reveal all of the contents of the book, but it's overall a well organized &, at the very least, entertaining book that anyone can pick up & understand & enjoy.
