Okay a sigil is an interface with a being.
What do we know about these beings?
They very much like to be called forth by humans, and enjoy sharing a physical body for the sensations it can provide.
They can possess and manipulate humans, and make them think the demon’s ideas are their own.
They require something in an alchemical state to form a STRONG manifestation, could be incense burning, could be animal sacrifice (life to death), could be chakra energy coming into your energy body.
So for a beginner with no strength and authority, he is basically making himself the bowl of copal resin or whatever, providing a yummilicious meal to any entity, and then trusting it will leave him or make all his dreams come true, and he’ll be the winner.
It’s like smearing yourself in minced beef them jumping into a tank full of piranhas, and trusting them to only eat the mince.
Just, like, don’t do it - don’t take candy from strangers, don’t leave your car unlocked in a rough part of town, don’t invite entities which we work with BECAUSE they will kill and manipulate humans, so deeply into your energy system you have no way to get them out again.
They are NOT fucking Superman, or Santa Claus sprites who just want every human to be happy and strong and ascended, except the baddie Chruch got all rayciss against them, and if you want proof that’s not some terrible bigoted rant, there is a whole Category on this website describing how magicians called these entities to ruin someone’s life and even kill them:
And no, this isn’t even an “only bad parasites do that, the real deal are all just so kind of marvellous” because hello, reality check time: the very same beings are being thanks on this very forum for destroying people the magician took a dislike to.
