This book is every bit as comprehensive as promised, but I found the rather large amount of information to be of limited practical value (if it has any practical value at all). This is because what is provided is incomplete.
The book begins with a "quick guide" which describes much of the theory behind the squares. There is a lot of esoteric information there, but from my point of view there is very little actual knowledge shared. For example: the author talks about elemental squares associated with planets and how we can focus on an element for a specific planet, but says nothing about how the different elements relate to the different planets. The author also gives basic information about how some squares have angels and djinn associated with them as well as some basic information about planetary and numerical correspondences, but information about how all these different squares are derived is at best incomplete and at worse sketchy.
The above examples are just a few examples and are relatively small compared to others I can give. The entire "quick guide" is like this. There is a lot of information in the text, but no real knowledge provided.
My biggest disappointment came when I read the "Benefits and Uses" section of the Quick Guide, where the author says that if a magic square was "created and empowered properly, a magic square is the only talisman you actually need to get wicked results". Then in the next paragraph: "I will be covering the complete process in depth in a book dedicated to this topic". In other words, we have all of these squares, whose derivation is incompletely explained, that are supposed to be powerful if used right, yet we will have to wait and buy another book in order to learn how to properly use them???
Frankly, I would prefer to have had a less comprehensive list of different squares, and a more comprehensive explanation of how the ones provided were derived and, most importantly, how to properly create and empower them. As it is, the book has a lot of information that, until the author publishes something that explains them more completely, is nice to have but not very useful to anyone.
I have seen and read several books written by Nineveh Shadrach, and I have a great deal of respect for this person. It is clear that Shadrach has a lot of knowledge and is someone worth learning from. Unfortunately, this book shows that there is a real problem conveying the knowledge of the subject of magic squares. It has more than 700+ pages of information that looks impressive but, in the end, is largely unusable even by advanced practitioners. Until something more down- to- earth comes out, with real practical methodologies for using these squares that can be tested by other practitioners, this book is going to sit on a dark corner of my bookshelf, gathering dust. I expect that Nineveh Shadrach would understand my attitude. After all, the first rule of Practice is that you should understand the Praxis before using anything in your Practice. Shadrach provides no real Praxis in this book. Practitioners, be warned...
