As a former armchair magician with some chaos magick experience, I'm roughly in the same shoes as you. I've found at this stage it's more important to find books that speak to you, that grip you and that you can't put down than the more difficult ones that provide solid information but are otherwise too hard or too boring to read. This is why many people recommend books by the Gallery of Magick because they are so accessible and treat beginners like equals, or Jason Miller's "Strategic Sorcery" because it's a fascinating read. Personally, I still like Peter Carroll's "Liber Null & Psychonaut" because of its refreshing iconoclasm but other people of a more traditionalist or olde worlde romantic bent may be put off by him because of this very reason.
I still don't like Franz Bardon's schoolmarmish style of writing but I'm slowly beginning to think that he may have a point as regards all these strenuous and time-consuming exercises he demands from his readers; others with a more industrious work ethic may think the guy's the bee's knees though. Donald Kraig is excellent but I immediately began to baulk when he begain talking about tarot and magical implements because they're just not my cup of tea (at least at the moment). It all depends on your mentality and taste.
So to my mind, it all comes down to subjective personal preference in the beginning. Ask me in a few months, and I will probably be knee deep in Bardon's exercises in "Initiation into Hermetics", no idea.
I've seen the gallery of magic stuff. I never tried it and decided to keeping struggling with Initiation Into Hermetics (lol) because I'm not looking to mess with forces that I can't control. I'm not going to try and summon or commune with an angel to ask for favors, or just invoke some unseen entity/force for the same reason. The kind of magic I want to do is to enact change with my own intent.
The the kind of magic practiced in Initiation Into Hermetics is very personal, direct, intentional, and something important I never saw in other books,
observable & testable. That's why it really interests me.
EXAMPLE (Using A Thermometer To Test For Changes In Room Temperature):
Initiation Into Hermetics
Step 5 (V)
Magic Psychic Training 5 (V)
Page 110 (Dieter Ruggeberg - 3rd Edition - 1976)
Repeat the accumulation and evacuation several times, and by each emptying, you will accumulate the fiery element all the more in the room. As soon as you are free from the element yourself, you ought to feel how the element is amassing in the room, and get the sensation of the room becoming very warm. After some exercising, the warmth in the room will become not only a subjective, but a real matter of fact and any person—magically trained or not—entering this room is actually bound to feel the warmth. A thermometer does indicate, how far we are capable to condense our imagination with respect to the fire, so that factually a materially perceptible warmth can be produced in the room. The success of this exercise depends entirely on the willpower and the plastic imaginative faculty. It is not absolutely necessary, in this step, to bring about such an amount of physical warmth that it can be measured with a thermometer. But supposing a magician takes a keen interest in working in this more spectacular way, he can specialise himself in this problem with the help of these instructions. The genuine magician, however, will not be satisfied with such an insignificant phenomenon, and rather prefer to further his own development, because he is firmly convinced that he can obtain much more, as time goes on."
But I may never even make it to Step 5 to do this test.
I just wish there was some kind of cheat code training method for the two difficult Step 1 mental exercises in Initiation Into Hermetics. You've probably already started practicing them by now:
1. One-pointedness (focus on a single thought for 10 minutes without any mental interruptions)
2. Vacancy Of Mind (empty your mind of all thoughts for 10 minutes without any mental interruptions)
I can't even get past the first one. I always get an interruption within 30-40 seconds. When I first started there was consistent progress, I was excited and enthusiastic, expecting consistent and small incremental progress. Then I just hit this frustrating insurmountable 1 minute wall that I haven't passed in a while (passed a few times before) and I don't see an end in sight. I don't want to spend 5+ years just trying to do that exercise, and then a next 5 years on Vacancy Of Mind if I even get there.
I might die before I even finish Step 1 lol. If I had a time machine I'd give myself this book when I was in my teens so that I could have built up better mental habits, and saved myself the trouble I'm having now.
