Ok so, I need to weigh in on this. especially this part.
To start let me just say, there has been times when what I wanted and asked for from a demon was not given and even the opposite manifested. In each of those instances that turned out to be for the better.
I have been studying for about 10 years now, sometimes out of the public eye and sometimes in. I was only comfortable coming out about my practice online about 3 or so years ago. When I did I wanted to appear as novice as I could to get different perspectives and it did assist me greatly.
For a good majority of the time, my study did not come from the internet but from spirits, entities, demons and from books, and from my mentor, who I will always adore and respect.
Now, on one of the incidents where I hOT The opposite of what I wanted, I wanted my ex back with all of my heart. I did a huge ritual and never got him back, instead I found out through an angry woman that he had been cheating on me the entire relationship and had STDs. She was his fiance, so apparently I was one of the other women. I wasn’t the one who gave him STDs but I was lucky that he did not return to me and that my ask was not granted. I remain std free and now am quite happy he’s out of my life for good.
On the somewhat different note there have been times when I have asked the demon for something that sounded completely illogical. Something that should infact be impossible. For instance, when I was younger suffered from ovarian cancer it was stage 3, I beseeched Lilith and she sent her son unto me. I made a pact with him and I’ve been cancer free for many years. I’ve had a few scares where we thought it was back so I still go to the Dr to monitor my levels, and keep a sharp eye out for any signs of reoccurrence but, still I’m alive!
I may get laughed at or called crazy but I believe it was Lilith and her son Koler who helped me defeat cancer. So please, while demons may not be completely infallible and sometimes they cannot or will not do things as asked, they are still very powerful.
i believe my will to live and their power was enough to turn the tides, so it really does matter about willpower, belief in yourself and them, as well as understanding that they are NOT tools/slaves/servants/pawns to just grant our every beck and call. They are beings, like you and me, with their own wants, desires, wills, and preferences.
If you come to them with the notion that they are evil, or going to serve you, then the likelihood of things backfiring is strong.
If you come to them with respect, confidence, and the will to follow through. If you come to them as someone who will work with them to achieve the manifestation, instead of someone who wishes things done for them with no work on your part. Well let’s just say, I am a strong believer that you get what you put in. If you just want things done for you and you don’t put in the right amount of effort or time, then like with any product in the physical world you get what you pay for.
Demons, entities, ect have the right to say no, that they don’t want to or that they will not or cannot change the situation or manifest a certain outcome. If you come to them not respecting their consent, then that’s on you.
I’m not saying that anyone here would do that, but I’ve seen it happen to more than enough people. I’ve seen what havoc disrespecting a demon can do to a person and their life.
P.s. in my specific belief, demons are basically deities/entities that have been vilified, slandered, or forgotten. They are quite powerful if you can properly align with them and their vibrations.
