This theory is addictive
This theory is like an earworm. Too addictive. Can't stop thinking about it.
The worst is its externalisation. The kingdom of heaven is within? The golden egg reflecting in yourself. Nope. According to this theory, it's all _out there_. That's negative.
I meet a pretty girl. She must be an incubus. I stub my toe? It must be an archon. And it's all day long.
What makes it so addictive? It seems to adapt to beliefs. "Every cloud has a silver lining." Yin/Yang, karma, Christianity etc. Now we're imprinting archons onto that system and it fits pretty well. It's hard to decrypt that way because once it's embedded you'd then need to lift out the whole original belief system.
I think the way out is to notice that it's quite materialist, and that taking ownership for problems is more productive, with a better track record. Seeing problems as coming from within isn't victim blaming if you're saying that to yourself.
