I do believe that this is part of the point.
This thread has become rather unwieldy, so I doubt it would be worth the time to write out much, but I will say that I have yet to experience a magickal tool so potent as the imagination. I’ve used wands, lit candles, walked around a circle while swinging around a sword, chanted all manner of incantations, and have even spilt my own blood in ritual, and none of these methods come close to what I have experienced using the Pathworking method of summoning given by this book.
It’s been a while, but I have read The Grimoire Verum, and it is true that the popular sigil you will find online for Lucifer (the very one in your profile pic) is a modification of the “original” Lucifer in Asia sigil from the GV. I have used this sigil, and again the experience within the ritual and the results that I received out of it pale in comparison to the Pathworking system.
Does that mean that I think this is the only way? No, but I do think that this is an incredibly profound and deep system that builds upon the work of Abraham von Worms (and likely many others after and before him), and was clearly crafted with extensive guidance, over many years, from the Demon Kings.
I also will admit that I find it rather amusing that so many here seem to find the idea of having subordinates to be repellent. It is the purpose of these demon servants to fulfill the desires of those who call upon them. They have a desire to serve their Dukes, the Dukes desire to serve the Kings, the three lesser Kings desire to serve Lucifer, and Lucifer desires to work with those who call upon him. None of the demons act against their will when you approach them as one seeking a symbiotic relationship.
I will also say that I do not see the problem with people selling pendants or other merchandise that people want to buy, or providing services that people are willing to pay for. Some people just want a tarot reader to tell them that everything’s going to be ok, and far be it from me to deny them their sense of safety. Others want to summon up legions of demons and wield immense power, but can’t be bothered to do more than watch a youtube video with catchy music, flashy colors, and someone chanting for them, and again, I do not think it my place to deny these people their fantasies. I believe that those who are born for magick will find the true arts.
