I have used both of these rituals, several times, and I have noticed great results each time. I have even worked with Lucifer directly, using the Pathworking given in the book, to this end, and have been nothing but pleased with both the short-term effects and my long-term progress.
The author states that you do not need to sense a presence for a ritual to be successful. All you must do is perform the pathworkings as described, and trust that the demons have heard you and will respond. I’m sure you’ve heard this before, however, so perhaps a story would be more effective in demonstrating the magick’s efficacy.
Sometime after I had been working with Lucifer’s Legion for just a few months, I had the pleasure of attending a somewhat small, but still enjoyable party. There I was approached by a woman who stood very, very close to me, and seemed to be almost in a trance. I, of course, flirted back, and after 10 or so minutes of this (with things going from just words to being more physical) we opted to play a party game together.
Across the table, a friend of mine and another young woman were playing against us. The woman whom I was playing with did not stray from my side, practically clinging to me, while the woman across from the table also began to flirt with me. The two ladies even got a little argumentative with each other, which I must admit was quite amusing. All the while, I was making double-entendre puns with the woman at my side, and at one point she whispered “not as close as I’ll be” in my ear.
Shortly thereafter, we went into a side-room to grab a drink. When I asked if she wanted to get out of there, she seemed a bit confused for a moment. After a couple more minutes of flirting, she said that she had some people she needed to leave with, and excused herself. Apparently, I later learned, her boyfriend had been there as well, presumably witnessing the whole affair.
After this I spent a moment in the side-room, where I was shortly joined by the other girl who was across from the table. We talked for a little while, and though we were not quite as physical, the looks she gave me were evidence enough that I was having an effect on her.
It was around this time that an old enemy of mine, whom I had since submitted to me, left the party as well. The evening had already been enjoyable enough as it was, but that was a particularly delightful moment seeing his reaction to my escapades.
Forgive the self-indulgence, but it would be quite the shame for anyone to read your post and assume that Lucifer would not be able to deliver the results that they seek. Perhaps you would benefit from the power of Bariol, under Amaymon, to embrace the power of patience. If you allow Lucifer to share in your desires, he will help you fulfill them. My doubts about that have long ago been shattered.
