As I’ve understood it, Evocation just brings the spirit in your general vicinity. Invocation makes them a part of you. I’ve only done invocations a handfull of times as a Wiccan. My general rule is to evoke until I get to know the spirit and consider invoking later down the line. This may have something to do with the Christian upbringing and fear of possession.
I chose Lucifer as the first demon I would work with. I set up the alter and chanted the enns expecting to feel his presence in the room. But apparently he decided he didn’t give a damn and just hoped on in. My body felt like it got hit by lightning and my aura changed to the same color the sigil was radiating. When Lucifer asked what I wanted, it distinctly felt like the voice was internal instead of external like usual.
It ended up being a pleasant experience after I stopped freaking out, and he accomplished what I wanted him to do. My question is, do evocations jump to full on possessions often or is this a case of a newbie screwing things up.
