This idea is compelling and underdiscussed. It helps explain why people that expect to find multiple personalities, demons, trauma, IFS entities, astrological-rhyme, past lives in Atlantis, etc. in their psyche are significantly more likely to find them.
Possible huge problem with psychospiritual journeys: Yes, there are deep structures in the labyrinth of my mind, and yes, I will have profound insights and fundamental shifts when I bring them into full awareness...
And yet...after years of self-work, I'm starting to suspect a large amount of the labyrinth is actually *procedurally generated.* Like a video game map that builds itself on the spot the further you travel across it
It would be like this sequence playing out:
1. I dive deep into the labyrinth of my mind
2. The mind goes "Oh! He's expecting to find some deep structures. Let me generate some of those that are consistent with the rest of me. Oh! He's also expecting to find some enemies there, so let me spawn some demons."
3. Lo and behold, there is more (eg) "unresolved trauma" to resolve
I think that this process is especially responsive to my motivation. So if I *want* to be in the narrative of Psychospiritual Journey, complete with Shocking Moments Of Insight? (subtext: ...so that I can procrastinate Finding A Job, Building Relationships, Pursuing My Big Scary Calling, etc) ...Well, then the mind will be happy to help. It will procedurally generate an infinite psychospiritual landscape for me to "discover"
I suspect the dynamic I describe above is why many psychospiritual delvers seem like they're just moving in circles. Yes, the mind is vast and there's tons of actually wild stuff in there to explore. Yes, imho Mind is humanity's true final frontier. But also...in some important way...you might be making it up
