Yes I do talk about it a lot haha, I think it was one of the first actual “work with entities” grimoires I bought and I’d already been awake for 24 hours at the time but I stayed up to read it cover-to-cover. That said, I may not be the best person to answer but I will do my best to answer your questions.
Doubt hinders your ability in everything. Where is your doubt coming from? Do you doubt that you’re going to get the results you want? Or do you doubt that you’re actually making contact with demons? If it’s the latter, the best thing you can do IMO is to tell yourself you are just pretending or playing make-believe, the way children do, when they can use their imagination to turn a cardboard box into a racing car or a castle. Act as though you have called the demon, they hear you, and they accept your petition.
If you doubt your results, I would suggest doing a petition ritual to Dantalion, Orias, or Paimon and ask them to remove doubts from your mind, or ask them to never let your mind linger on doubts. I spoke a bit about this here.
You can try using an astral temple (search the BALG forum for “astral temple”), or you could try another method, such as a pathworking. I believe there is a grimoire out there which contains pathworkings to the Goetic demons (hopefully someone will jump in and mention it because I don’t own it and am unsure what it is called or who wrote it). Alternatively you can use the evocation keys in DoM as pathworking steps. Pathworking, in short, involves going into a trance/altered state and then “walking” through a series of images or other sensory impressions to encounter the demon in question.
Hard to say, since I don’t use DoM exclusively, and I tend to layer rituals for the the results I want. And those other rituals might include working with angels, genius spirits, gods, other assorted entities, the Law of Consciousness, or my own experimental rituals.
In general it is best to ask for one thing at a time, wait until you get the result (or until sufficient time has passed that you are sure it will not happen - like 6-8 months might be a good benchmark for waiting).
Also, it never hurts to build up relationships with a spirit. Start with small requests which have a lot of avenues of opportunity to manifest and just need a nudge in the right direction. Give thanks and give the offering you promised. Build a good working relationship with a spirit if you intend to go back to them time and time again.
I can’t personally say whether one spirit or another is going to get annoyed if you overwhelm them with requests one-after-the-other, but if you don’t even give the original ritual room to manifest, it seems like a bit of a waste of time. E.g. Don’t call Sallos and ask him to make X your girlfriend, then call him up three days later and ask the exact same thing again.
Really this comes down to the individual and the kind of relationship you build with each entity. Like imagine if you have a new coworker, or a new classmate at school, and you talk to them once and they seem OK, and then immediately they assume they’re your best friend and suddenly they’re following you around everywhere you go, trying to talk to you all the time, trying to make friends with all your friends, inviting themselves along to your planned activities, etc., and you’ve only known them for one week. Would you get annoyed? Maybe you would, or maybe you’d be flattered, depending on the person. Does that make sense?
Me personally, I have a specific pathworking to Lucifer (one that I unfortunately cannot share) and some other pathworkings to a handful of gods and entities that were either channelled and shared with me by other practitioners, or discovered myself through experimentation.
In general, if I wanted to speak with a demon or entity and I couldn’t find a system for contacting them (on BALG or via online search), I would read about them and try and find a sigil or seal for them, or an image or symbol that represents them, and anything else related to them. For example, I made contact with a god of the Māori pantheon this way and was given a pathworking to him. For non-goetic “demon”-type entities, there are also grimoires like Lucifer and the Hidden Demons and Kingdoms of Flame, etc., neither of which I have read, so I can’t personally comment on, but I am certain you will find a lot of content if you search the forum for those titles.
Edit: There is also EA Koetting’s mantra/chant to call forth any spirit, #4 on this blog post.
Humans are of spirit too, but I think it would take a great deal of power to push planets out of orbit. And referring back to the above, who is to say that planets are not conscious in their own right?
I guess I partially agree in that consciousness is fundamental and results in matter, and not vice-versa. But with respect, I am not certain I understand your point, although I’m happy to discuss if, if it doesn’t result in derailing OP’s thread.
