Alright, trying to unpack Seto's ramblings:
"Perception is like a folded up map. The moment it's unfolded, it seems as though the location was already fixed. But you should know that is only an illusion.
Distortions that reject language, forcing the understanding of their structure into a mold, they consume definition"
"Just when you think you've touched it, the outline collapses and you lose sight of it"
What I gather here is, any attempt at understanding a ghost (a "distortion") is your monkey brain trying to make sense of things it has no concept for, shoehorning your own concepts and preconceptions into it ("
into a mold"). Further prodding and investigation will reveal how fuzzy and weak your understanding, the "outline" of your definition/mold for that ghost, really was, and so you're back to square one trying to apply a different mold.
"Symbols cloak their form in disguises, wavelengths get disturbed and infect the thoughts."
"Phases fluctuate and existence interferes, yet meaning continues, on the reverse side of the meaning you're aware of"
What I think he's getting at is, the ghosts take advantage of these attempts at being "understood", donning any concepts applied to them as a disguise, and having this conceptual disguise spread to others.
So, hypothetically if someone met a "formless" spirit and went "omg, it's a kitsune!", the spirit would now take the form of a kitsune on future meetings with other people, and be further defined by other people's pre-conception of what a kitsune is.
Like a tulpa, these spirits (or rather their disguise) is shaped by human perception and conception, though (unlike most tulpa), this is on a collective, cultural level.
Concepts infecting thoughts of others.
All of this however is a superficial understanding, hiding the real, unknowable definition of what the spirit and it's motives actually are.
"From the start, there was never a partition. All things overlap."
This I'm not sure about. There's the obvious talk about there being no "partition", no tags or molds or definitions that can ever truly apply in helping categorize and thus understand what a spirit is, because ..."all things overlap".
As in, all spirits, underneath their disguise, are all the same I guess?
"I merely stand in the gaps"
"As long as there's margins left"
"So that distortions don't cross the barrier"
Whatever it is Seto does to exorcise spirits, it relies on these "gaps", the "margins" in definition and categorization, the "holes" in a spirits disguise.
The part about crossing the barrier could simply be about preventing their influence on the real world, ...or it could be worry about something that may happen if a definition manages to be solid enough that there's no gaps.
But I'm probably reading too much into that, and it's just the former.
...And then there's whatever the fuck Romm is talking about with modding bugs out.
I may dabble in
NofNA-speak, but I don't speak Skibidi-talk at all.
