It's about the Kabbalah (notice there's almost Allah in there? Mixing of cultures yadda yadda) and so-called God-levers. Knowledge and his own practical insight into working with them. Each letter of the latin alphabet has meta-physical connotations and he shares his experience with them. I'm only 75% through the book, but I quite like it. Cute pictures too. It's only 10 bucks and you can get it on Amazon. I wonder if you can create magical spells by stringing the letters together, hmm... The words don't need to have a traditional meaning, we can create new ones and give them meaning, yay! We are creative creatures
If none of that rocks your boat you ain't the GOAT. No but seriously, his description of the various astral realms are quite fun to read and insightful. Also he made sure to update safety warnings lost in original translations. You can get some nice pieces of wisdom here and there. Keep in mind everything is written with his own personal bias towards the world. As is the stuff I write. Hehe.
And if that doesn't satisfy you, you can still get some ideas for your next Dungeons and Dragons campaign or lose yourself in imaginative fantasy like you did as a kid reading your first good book.
In short, I like reading it and recommend it to others.
