I found a pdf copy of
Lucifer and the Hidden Demons by Theodore Rose among the interwebs. I'm strongly considering the purchase of the Kindle version at this point while reading the pdf I found. Of course, the author says that his point of view will be controversial. I do have a question about egregores, however, based on something he wrote:
"When people use false magick [as defined by the author] to contact great spirits, such as Lucifer, what they get is at best a splinter of the original, a fragment channeled through an egregore. It may feel like Lucifer, and it may give you a strong sense of its reality. Egregores, once formed, want nothing more than your belief, because that is what sustains them, and so they offer sensations of supernatural contact. This does not mean they have the power to grant the wishes requested of them.
"I find that people who connect with these egregores of the great demons become overly fascinated by them, too deeply attached, and before long they are worshipping them with love, feeding the egregore and obtaining little in return. ..."
The egregore as described sounds quite parasitical. So, in general, if one seems to be susceptible to having a lot of "feelings" during their magical workings, yet lacks results of any significant and provable nature, then quite possibly the magician has been deceived by a parasitical egregore? Personally, I seem to be dense as a rock when it comes to having feelings at this stage in my development, but I'm also not prone to strong emotions anyway.
