So I’ll share what my experience is.
There are two instances. One is when working with a new spirit and the other is when evoking someone you have a good relationship with.
- New Spirit - I highly recommend a good and bulletproof Preparatory immersion. I usually do this by researching the Spirit and seeing what they like or don’t like. What they’re like. However take all this with a grain of salt. Because everyone has their own experiences and you will have your own. Second is I medtate on their enn for a minimum of 45 mins everyday for a week. This helps me make a connection. I usually get tingly, they start coming to me in my dreams. You get a feeling of what they feel like. Same as how you would get with humans.
Then during the evocation, when everything is set. With many spirits I already feel someone watching me, feel something from the corner of my eye. Then when I start to chant the enn. I get tingly all over, recently this has progressed to a strong pressure on my third eye and tingly and pressure in my ears. So I keep going. This progresses to a feeling of a blanket that descends or a “wall” that is around you, but the wall isn’t a solid wall, a wall of “spirits”. It’s a strong irrefutable presence. Each spirit has a different energy. Initially they all felt the same, but as you evoke more, you can gradually tell the difference. This is what it feels like. Atleast to me.
- Spirits you’ve worked with - With these, you’ll feel them there much stronger even before you start. I’ve been working with Duke Dantalion for a while now and last Friday when I evoked him during the eclipse. I didn’t even get through one Enn repetition and he was there. I felt it very strongly.
I would evoke often, very often. Mainly to learn and develop your clairs. Check out this following post by @Mike_Bee down in the top 10 posts or so he talks about working on your clairs with Demons, I’m currently doing it and it’s helping me a lot. I highly recommend it.
I also used the following process by Lady Eva, about Belial’s Gateway Symbols. I’ve had great success with that as well.
