Anyone can learn how to summon a demon. It is much easier than movies portray. As long as you do your research beforehand and keep an even temper, then you should be able to successfully communicate with creatures from outside of this universe.
What To Do Days Beforehand:
The first thing you need to do is choose which demon you would like to summon. They are not all the same so you need to make your decision wisely. After all, some are going to be more pleasant and understanding with you while others are going to be violent and destructive.
Make sure you do your research well ahead of time — and make sure you are summoning them for the right reasons. You should not be exploiting them. You should be treating them with respect if you want respect returned.
You cannot summon a demon without making an offering. After you have figured out which demon you are interested in summoning, then you should acquire a certain set of items that will make it feel more comfortable. For instance, if you want to summon Mammon, the demon of greed, then you should try finding an owl rope bracelet to represent trust between the demon and yourself.
The demon might choose to speak to you telepathically, but to be safe, you could always buy a scrying mirror to help it communicate with you.
The last step is to find an empty space where you can prepare the ritual once you are ready. Make sure it is a space with a locking door. You want to be completely alone without any disturbances. You also want to have hardwood floors beneath you instead of rugs so you will be able to write across them.
What To Do Hours Beforehand:
Wait until it grows dark outside, because it is better to perform rituals at night than during the day.
Make sure that you place incense around the room with a scent that your particular demon is associated with. You should also choose five candles of the same color, a color you think fits the demon.
Next, draw a pentagram on the flooring beneath you. To do that, create a large circle with a star in the middle. Make sure your lines are all perfectly straight by using a rope, a ruler, or anything else that can help guide you.
Place the five candles that you have collected onto the five points of the pentagram. Light each of them to represent the different elements of the earth — air, water, earth, fire, and spirit.
Lastly, print out the sigil of the demon you are trying to summon and memorize its shape. You should be able to close your eyes and visualize it. You should have it engrained in your head.
What To Do In The Moment:
Close your eyes and picture the sigil of your demon. As you are doing this, recite the demon’s prayer aloud. It goes like this:
“Lord Satan, by your grace, grant me, I pray thee the power to conceive in my mind and to execute that which I desire to do, the end which I would attain by thy help, O Mighty Satan, the one True God who livest and reignest forever and ever. I entreat thee to inspire [name of Demon] to manifest before me that he/she may give me true and faithful answer, so that I may accomplish my desired end, provided that it is proper to his/her office. This I respectfully and humbly ask in Your Name, Lord Satan, may you deem me worthy, Father.”
If you successfully make contact with a demon, remember to remain polite and respectful. You can make requests of them, but do not demand that they help you or pressure them into doing so. Treat them the way you would treat any other living creature.
After they vanish, you might feel tingling in your body since you had contact with an extremely powerful energy. That is normal. That means everything you did worked.
