If it works for you then that’s great. I tend to not trust occult works that have not been tested by groups of working occultists whom I believe to be of sufficient knowledge and skill for my standards. It’s the same for scientific work. I wouldn’t trust something that hasn’t made it through peer-review, and by peer-review I mean people highly educated in the subject matter. I wouldn’t take a drug some guy cooked up in his garage, and that tends to be my attitude towards magick.
I would never claim to have the “one true way” for anything. If I did I would hope that someone would point that out and call me out on my bullshit. If you read the book you mentioned you will find that the author(s) makes no such claim either.
What they do is point out that the sigil you most commonly see for Lucifer online nowadays is itself a distortion of the original Grimoire Verum sigil for “Lucifer in Asia.” There is a “Lucifer Pentacle” that’s supposed to be the main image, which I have used to call another demon. That ritual worked, but I can see why the author(s) believes it to connect you to a mere shadow of the full powers of Lucifer, which are much more far-reaching. I have tried using the “Lucifer in Asia” sigil, but nothing really happened. Perhaps that is just because the invocation I used was extremely vague and read more like a devotional prayer than a magickal formula, but the energy from that sigil is much different than what I experience using the LHD pathworking.
The author, who (presumably) represents a group of people who (presumably) have worked together and with these demons since 1955, also claims that Lucifer magick goes back far before biblical times, and that much of the “true knowledge” has been passed down in secret, and was presumably accurately recorded most fully in The Abramelin and in private grimoires hidden from the public, which they presumably have access to. They claim that the GV is based on corrupted ideas and corrupted sigils, corrupted here meaning distortions of ideas and images that represent the full breadth and depth of the power of Lucifer, not just a mere slice of it. I am not a trained scholar of history well-educated in these matters, so I can only speak from my experience and place my trust with those whom I find trustworthy. The quality of the work presented in LHD was sufficient for me to give it a try, and the results have been abundant and life-changing. I have also read the latest translation of The Abramelin, and agree, bearing in mind my limited knowledge and point of view, that the text was truly intended to pass down the demon names and hint at the power of the magick. Perhaps there is more in the text. I do not know, as my ability to study it is limited by my limited perspective.
I don’t expect many people to like my true personality, which is reflected to a surprising degree by the tone of LHD, but just because you do not like the way someone speaks does not mean that they are wrong. This reminds me of a thought I’ve had recently. It never fails to amuse me when people try to assert themselves as an authority by quoting the number of years they have been involved with something. I could give two fucks how many years you’ve been doing magick, what I care about is what you have achieved and the knowledge and skill you have acquired. I tend to learn things much more quickly than other people because I have cultivated the ability to learn and enrich my mind with a variety of quality material that challenges and expands me. People with more “experience” than me get all defensive when I can perform better than them when I have been doing the thing for less than half the time they have. “Ah, but I’ve been doing this for twenty years sonny, you should listen to your elders! Look at my mediocre results and my equally mediocre life, don’t you have so much to learn from me??” Yeah, fuck off. It’s not my fault if you can’t handle the truth when it is laid bare before you.
