Query: A good booka nd not too simplified or dumbed down

I had my doubts at first that this book would be more than just a novelty addition to the Necronomicon series, but i must say that in jsut working with Nibiru things did stir around me and it all became a very scary affair, that said, the results were desirable and that reminds me just now that i should go back and recharge the sigil. It is defnitely very Goetic in nature, but whereas the Goetia cause actual entities to present themselves before you, the seals of Marduk are more like unnerving forces coming from under the earth. Interesting stuff to utilise but avoid the temptation to just play around with these things, whether ancient or contemporary.
