This revision of the Satanic Bible by Michael Aquino is better written than Anton LaVey's Satanic Bible in the sense that it actually credits its sources. I appreciate that, more than anything. It also goes into more depth when explaining the philosophy of the Left-Hand Path and the theory of Greater Black Magic and Lesser Black Magic. At times, the theories and philosophy don't appear to align with what is written in the original Satanic Bible - but I don't mind. The idea of subjective universes and objective universes, and how either can be influenced and how the five dimensions play a part in all of this - the theory fascinates me - even when I find myself needing to reread it a few times in order to understand what he's talking about.
At times, it seemed like I was reading a bible for the Temple of Set. Although Set, the Mindstar, and Xepher are all very interesting and even quite relevant to the LHP, I would have rather stuck to terminology found in the original Satanic Bible.
I'm not convinced that Aquino's interpretation of the Enochian Keys (or The Word of Set) is any better than LaVey's (okay, no, it is better than LaVey's), but I'm not sure how it's any better than Crowley's. It just seems like one more interpretation.
I also appreciated that it was organized into four sections just like the original - the Book of Satan, the Book of Lucifer, the Book of Belial, and the Book of Leviathan. The extras at the end of the book were fascinating, although I do not know how they were relevant to the book as a whole. All the same, I really enjoyed reading Aquino's recollection of how LaVey showed him a hole in the basement, leading to a tunnel, which could likely collapse at any minute. The skeptic in me doubted parts of the story, but hey, I'm a skeptic. I do not doubt that there are tunnels beneath the ground because that's quite common. Seattle has an underground city, and anyone can tour it. I simply doubt that LaVey believed there was anything mystical about it. He was a showman, and I'm more willing to believe that he was putting on a show for Aquino. But who am I to judge? I was not there. All I can have are my doubts.
Overall, I highly recommend this book. Even if you disagree with the theory and philosophy, if you want to know anything about the topic, this is the book to read.
