Bemache yeah I was thinking about that sort of thing after typing that. I'm reminded of something about left-hand path occultism, not to say I know a lot about about it, where they dominate demons, or emanations of demons (and tulpas are called emanations or somehing like that in Tibet), and they have strong enough will to dominate the demon, and they make things become part of them. That reminds me of merging with tulpas, or merging with tulpas reminded me of that, or something like that.
So if you wanted to conjure a poltergeist, something with physical effect, well maybe you'll be drawing a circle and getting the candles and it'll get magical and you'll want to know what you're doing. Maybe if you have a mental image or a sigil of the poltergeist/demon/whatever you can then do forcing and parroting on it, and merge it with servitors and things, until you have something that's not hostile to you and has its own intelligence and memory and will and personality, and can knock things off shelves to amaze scientists wew lads now there's a plan.
Albino Elephant ah a lot of ability or time, I'm hoping for a shortcut where you can be someone who's not a wizard, but has a cardboard ouiji board (basically just a normal joe) he can use to get stuck with a poltergeist, but he manipulates it with mental techniques tulpa people have, and there you go, in a week you've got telekinesis xd (edited)
