Theories of Magic

Dear fellow members of BALG,

I’ve been wondering about the metaphysics of Magical theories recently and was wondering if anyone could point me in the right direction. I’m curious how Magic explains existence, reality, cosmology, perception, truth, etc…

I want to alao understand the mechanism behind summoning angels, demons and other spirits. Where do they dwell? What are they? Are they composed of a specific substance? How do they react with the material world if they are incorporeal? Etc…
How do we explain all these things?

Any help would be appreciated. If you know of published articles, books or websites please share them here. I’m sure others will also appreciate your contribution. Thank you.
