Mulberry’s warnings are quite valid good, wise advice.
As I fellow writer, when you create a story, like a novel, you’re already operating in the astral and mental realms. You are a creator of a universe with various characters put in settings with a plot and subplot driving them all. Readers are already providing energy in the form of imagination, intent, and desire to see how the story unfolds.
Creating characters in a story is similar to how servitors and egregores are created.
Why limit yourself? How about using the energy of your readers to manifest the characters and the world of your story? Yes! That would be the ultimate alchemy and magick. The principle is similar to that of a hypersigil.
L. Ron Hubbard created a religion called Scientology out of his sci-fi novels. Hmm? There are real Jedi masters now based on the fiction of Star Wars. How many countless technologies have been inspired by the fiction of Star Trek? We’re using some of that right now, in fact.
I’m not saying to start your own religion or try to change the world.
Expand your ambitions. You’re a god. A creator of universes. Act like it!
