The book is mostly visualizes of landscapes. No candles, no invocations, not even descriptions of the demons. Pure simplistic. This is what you want, visualize this in this process. The group that writes books like this, the gallery of magick, are not my favorite actually. I’m a fan of the modern day rituals where you speak invocations.
The visualizations have worked a few times, but I don’t necessarily feel like I’m doing magick at all. I’m a hypothetical beginner with no knowledge on demons. I have no idea who I’m calling upon or what they are life. I don’t even know how to picture them. I actually have knowledge and research, but not from the book.
Dealing with ANY spirit or deity should be considered serious. You should know who you’re talking to, what they’re about, and what you’re getting yourself into. Though. not every spirit is dangerous. Some can be quite benign. Some are just there to help you out as opposed to being freelancers. However, learning about a spirit not only helps you determine if it’s good or bad for your intent, but also helps you identify the spirit and feel its energy. What this book does it that it says “Oh you want this? You should talk to him.” It doesn’t tell you ANYTHING about the named demon. It just expects you to go up to the demon and say “Could you give me this?” That’s basically it.
You are contacting a demon without knowledge of it. Theoretically, you shouldn’t be safe. However, you are, and depending on the situation and options at hand, the book works. You do not feel close to the demon nor do you get the feeling that you’ve actually done anything magickal. And yet, it still works.
The book’s worth to you should be based on what you want. If you want quick (possible) answers to basic problems and don’t care about getting closer to spirits, try the book. If you want to become closer to the spirit you are calling upon, go for something else.
All of this is my opinion. Others may feel different. The Gallery of magick isn’t so much for serious occultists. They offer quick fix books with little to no substance. Again, all my opinion.
