I finally found a copy of this so-called forbidden book, with all its forbidden knowledge, and it turns out to be all lists of entities I seriously think were fabricated for this "grimoire". Maybe some of them used to be pre-Judaic deities, but that does not mean they are deadly dangerous demons. Pretty much, the point of this book is to do months of ritualistic cleaning, to prepare yourself to summon up a "demon" in the thousand names of God and His angels, so that you can magically/verbally/spiritually abuse/beat same demon into compliance, and ask his/her enemy angels to drag him/her to you after more beatings...so you can ask him or her for petty little things like getting a booty call or making women appear naked before you. Honestly, could you blame an entity for being furious with being summoned? I would say avoid using this book as a spell tome.
