Selling your soul is easy. Just tell the devil you want to give him your soul. 
However, you will miss the point of the Creator creating humans after all His creatures.
You are a king, humans are Kings. Fear and false teachings do not want you to know that fact and for you to act on it.
So skip the soul selling part and ask the spirits to do what you want and they will do it without any questions asked.
How I wish we ( humans) know who we are!
You can “sell your soul” as a form of commitment for a pact to show a demon how serious you are and look at it that way, I wouldn’t recommend it because their is a myriad of demons and angels who want to work with you and I lowkey believe committing to one entity is overrated.
In Hollywood contract people have written pact contracts that essentially are written so that whom ever is writing gets to use their power rather than the actual person. So it’s a powerful enhancing spell that opens people up into adept-hood without their knowing. Or so I’ve heard.
I think you are mistaken, my friend. Even if you did ask for something there is a problem, the language you use to speak is in itself a code, a means of communication to filter out what it is you want and dont want in order to communicate: states of being, emotions, feelings, and memories/visions. The likelihood that a new magician would be able to communicate this well enough to get exactly what they want is slim, heck it’s even hard for a more “experienced” magician like myself that’s why we employ the aid of rituals, decoration, sigils, intent, etc etc. It is to further solidify and seedling idea into a full-fledged idea and state of being that matches up well with our will and intentions!
Who’s to say we didn’t come first, and what creator are you referring to GOD, YVWH, Allah, Satan, The Universe, source, ourselves.
Do you see my point here?
This person probably has a very different version of reality than you.
So, belittling their current world view will probably not help as they are NOW just realizing their power or have realized it enough and awoken to the fact they are a living god, now acting upon that new and profound realization to the best of their ability!
Well, I hope you don’t let it hold power over you for too long (if you hate it as much as you say) thoughts and beliefs are possible to change, but you must first be willing to make the necessary changes and plunder into the unfamiliar. For you that sounds like magick, but for others it may be simply be questioning their current faith or practices.
I know exactly what you mean, I thought everyone on here was absolutely nuts for summoning demons, now here i am telling all my friends the second I have an opportunity, blabbering on about the benefits and upsides!
I have to agree with Knight here, it is through humanities perversions that we end up with so many problems when it comes to religions and established ways/teachings of life (like Confucianism).
Have you ever read (one of) The Bible(s)? I mean, in my opinion, it is one of the greatest reflections of reality. Profane, contradictory, and at times a marvel.
It truly is, sighs in admiration one’s hell in a book…
As it looks in the instance and maybe a long involvement that Christian teachings make things so rigid.
However, I believe Christianity have made us enlightened. If you have read the Bible you find some weird spiritual practices esp. the Old Testament. No one will teach that because it is meant for the inquisitive.
Study the Catholic Mass, and what they say, there ceremonial activities and there “Exorcisms”, you will instantly say occult practices. 
Christianity is peaceful, enlightening and a powerful religion where secrets of the occult knowledge are for bythe one who have undying thirst for knowledge or who have a natural affinity to the spirits.
Those who preach against summoning demons say this because of the records and experience on how demons are worshipped which is against the commandments.
As I will always say, we are gods because we are created like God, we are both divine ( celestial ) and human.
I am not stuck within these beliefs and thoughts. But they influence my actions during ritual when I am just starting it for the first time. Like when I did Succupedia’s Letter of intent ritual. I couldn’t meditate afterwards because I was shaking uncontrollably. I would have loved to do the ritual to the T but I couldn’t because the “demon bad, angel good” shit has been in my brain for ages it seems. But with time and confidence I will rid my self of it.
I don’t like Christianity, I used to; but not anymore. I can’t stand it for some reason, I don’t know why.
Do yourself a favor, DO NOT FEEL BAD about a consensual relationship with a lovely soul, I understand new beliefs and faiths can be scary ESPECIALLY when you are threatened by a death from all your previous programming! I can appreciate Christianity though, far from perfect, but it taught me basic human archetypes and a decent moral code (far right and far left aside).
How would I properly sell my soul for something in exchange?
You don’t. That doesn’t exist. And if it does, it’s a pretty bad idea and you shouldn’t do it. If you want something, why don’t you offer food like the rest of us?
A) you cannot ”sell your soul“, that is a myth. You can, however, enter into a pact or some sort of allegiance with spirits, but they neither want nor need your soul.
B) there are already a few threads about this, if you use the search function you will most likely find one that has answered this question (there are also many threads about pacts).
Wow, it’s been a minute since we had an uninformed ‘selling souls’ thread.
Ok thank you
You can sell your soul actually, I’ve had experience with this on many occasions. The act of selling your soul is basically like “you own me for this amount of time” either within the reincarnation or when you’re done with this life and as your ‘true self’ in this time frame if it’s not permanent they can do whatever they want with you, if it’s permanent the same case still stands you become whatever they want you to be. It’s called soul selling mainly because when you’re done with this life you are your soul, your true self, and they own you for however long the contract says. There are many entities that are fine with owning souls, many occultists have this rose colored mentality that entities dont do these things but that’s imo because many still have to experience more.
You can’t reincarnate without their permission among other things.
Selling your soul is far from a myth lol, however it’s not advised to do so, soul selling is still a form of contract, it’s like offering something in return for something else and you get it back when the contract has been fulfilled or if permanent you get what you want but you give up your free will and open yourself up to whatever outcome happens to your soul be it becoming food for another entity, being in servitude, or like one of my guides who sold their soul to me prior to this life and in doing so they became something of an advisor/guide for me, but in this life I aimed to befriend them which I have.
your soul isnt literally taken from you, it’s basically marked with whatever symbol or sigil the owner decides on to reflect their ownership of you.
I was reading about someone who decided in order to get some girl he would give himself over to Azazel to do the lake of fire ritual. He had a dream that night of being branded with a bunch of sigils by Azazel. IMO I think he legit got fucked.
Pretty much, though there are some entities who will treat you pretty well during the ownership, but only reason I don’t advise it is because a lot of people do it on a whim, not getting to know the entity or anything of the sorts.
Hell I’ve seen a soul being eaten in my years of doing this stuff, of course the soul wasn’t reincarnated here but it was during my time in projection. Some even form bonds like me and one of my guides who I mentioned sold theirs to me prior to this life and it’s been this long and we’re pretty much friends/formed a bond, he has free will and he actually wants to stay my guide.
Soul being eaten? So it’s like gone/destroyed?
The same way you’d sell your body to complete strangers who have vast power and almost no accountability: be willing to eat whatever they want and pretend to love it or pay the price, and do whatever they request, no matter how vile, and no matter who or what to, and the only difference is, it’s forever, and you can’t opt out via death.
Still sounds good? 
Yeah, ofc energy can’t be destroyed but rather transformed into something else, so the energy being transformed into a food source for an entity it ceases to be a soul, but that kind of energy.
Don’t be desperate for results. That’s how you get into some serious problems.
Exactly lol, the spiritual is pretty “do taboo shit” lol though I find it pretty cool, the selling souls and such, I’d never sell mine but the act of that being a way of gaining say followers is pretty interesting.
