i came back to this thread after... months expecting it to be the same atheist vs retarded christians debate and saw this. this thread has just took a turn for the fucking awesome.
isn't this 'power from satan/demons' pretty much what christians claim about the feelings they get when they talk to their god except, you know, more appealing to the gothic/teenagers? so what exactly does this black magic do? how do you interact with demons? what do you talk about when you communicate with these demons? how do i try black magick? im not trolling or anything. im genuinely curious as an athiest/person with a scientific background education.
Haha, I think you might be surprised when you see satanists, a lot are neither goths or teenagers

Interacting with Satan and demons gives you a feeling of power, in control and therefore aids your thoughts, making them much more intense. They aid me in how to control my mind, but also allow me to know what is my physical life and the astral plane. They are also there when you feel down but do not want to control it, for example a heartbreak. You will sense them very strongly, especially Satan and he will help you to get over it. Satan and to a slightly lesser degree demons are there to guide us when we are down in the gutter. I guess that can be related to the feeling after praying to God? But Satan can be felt without the aid of a prayer.
Black magick allows you to control any emotion you have, from pain to happiness. It allows you to control your mind to such a degree that thoughts feel like a reality, you can walk around and generate buildings to incredible detail. Almost like having a dream, just a lot more realistic. Just like real life I guess. In this plane you can also interact with other users, giving them certain bits of information which they will remember.
Black magick also allows you to manipulate people to a great degree. With knowing how to control ones own mind, it is very easy to control others when they have no idea on how to protect themselves from it. You can give people an idea which will eventually take a form. You can make a person think they are in love with you quite easily for an example. Another is you can use a curse on someone, giving them an idea which can help destroy part of their mind, such as forcing them to believe in something so much that they let their real life go. You can manipulate their minds to really mess them up in life. I tried a curse on one person, which required a ritual requesting help from Demonic powers with guiding as much hatred to that person as possible. The person, who was in a normal position in life, girlfriend, job, house, murdered someone about a week later and got placed in prison. Could be a coincidence who knows, I'll leave that up to you to decide.
Black magick some say is a gamble with sanity, you are trying to control ones mind to then change situations which is a very real effect.
Interacting with demons is very easy, you can pray to satan, and(/or) meet them in the astral plane of your mind. They are not these foul beasts that they are claimed to be by religious bodies, but are quite often very beautiful beings. You have to show them respect or they will destroy some of your mind, but you can quite often set up a mutually benefiting agreement with them. You can quite easily talk to one about whatever you like, but often you communicate asking for assistance in one way or another, always making sure to show respect and devotion.
I really warn you about trying black magick because as stated earlier, it can be a gamble with sanity. Some practitioners can begin to lose sight of the physical reality, and can become trapped in their thoughts. Just the idea of black magick has destroyed peoples lives. For black magick you have to first believe in its effects 100%. You have to accept that it is a very real concept and it does work. You then have to be able to control your mind to be able to at least generate something that feels real which can take a lot of time. A lot suggest the first thing to do is to create a temple within your mind of dedication to satan. It can be of any form you want as long as you can vividly feel it. Can be any material, any size, any look, anything you want in it. You then need to ask Satan to bless it. Multiple meditations and thoughts will strengthen this in your mind until it becomes a reality. This temple is then where you can invoke and meet demons to ask any questions you want. This is one of the most basic, yet essential black magick 'spells' to perform. When I say basic, I do not mean it is easy though, you may find it difficult to visualise your temple to such detail, and it will take time.
There are easier black magick 'spells' that work, as it is just the ability to control your mind. So an easier one would be say trying to control some emotion like pain, for example if you turn on a shower to boiling at the point were you can't stand the heat, then try and get in the shower without feeling the pain of the heat at all.

Hope that's all of interest, feel free to ask about anything else you want to know about
