You are correct everyone is both part body part spirit. And spirit speaks through many people.
It sort of works like this, spirits move from person to person training them, once they are trained to be a certain way, they move onto someone else.
They work in a hierarchical system without free will, mostly minions of larger worse things.
And if you try to free a person without breaking the hold from the bad thing, then other things come back and try to train them again when the person tries to do what they think is best by better thoughts.
So if you find someone that is still being trained, and not just acting in a trained pattern, you can find an entry point and trace it back to its leader thing that is pulling the strings, you destroy or flip that thing, and many of the minions can be set free. And once free they still have what they learned, but also choice and better thoughts on what should be done. Although they also have to find a better source to think on once free.
Part of the problem is that the people already trained by them still act in same patterns. So even if not having strings pulled, or even if what trained them is gone, they still serve those things.
Basically that is why it can take years to find entry points and track back to the sources deceiving and hurting people, in a way that makes a difference.
And there are many sources that suspend in things like songs and stories, that trace back to better things that you can get strength and comfort from, many in songs and stories for instance. Probably why the concept of a picture holding part of a soul occurred, since entry points can be suspended in pictures and things like that, and that was probably seen by people that made those comments back then.
So many songs and stories stay entry points to different sources, even if seen from a different temporal location. Even if watching a recording or an event from a different time. However they can also be reloaded or diverted and that is done in many edits by people, adding in their own entry points when they make changes to things.
"I left my body laying somewhere in the sands of time" Explanation of entry points in many songs and stories.
Two powerful entry points to courage and love in songs.
