To put this in a more physical lens, modern science is revealing that thought is a field. I'm strapped for a good source at the moment, so you'll have to bear with my half-recalled youtube popsci, but basically: They can put a sensor a couple feet away from your body and it will still pick up your brain waves as an EMF (ElectroMagnetic Field). There's other science I've read that suggests the brain doesn't just broadcast, it receives. So your thoughts are a mixture of internally and externally generated fields interacting in your immediate space. This isn't very woowoo until you consider that it implies telepathy is happening pretty much constantly throughout the human experience.
I
believe my source for this information is Bruce Lipton on youtube. He's an epigeneticist who has observed cells under a microscope responding to this field of thought, similar to the famous
. Essentially, your body responds to your thoughts, but only a fraction of what you "think" really comes from yourself. A lot of it is baggage programs installed by people in your life, little moments in childhood or your early career that influenced you and are now still floating in that sphere of thought unaddressed. Some of it is internally generated, but it's the quiet part.
Let's make this a little more woowoo. Everything has an EMF. So everything interacts with your thought-bubble EMF. So it's not just people, it's objects too. It kinda brings some physical grounding to the idea that there's a spirit inside of everything. Speculatively, if we imagine that "thought" or "consciousness" manifests as an EMF, we could imagine that everything with an EMF is conscious, suggesting thoughts can affect inorganic matter (as demonstrated in the ice crystal experiments).
Of course, the
real answer to your question is: It's you, it's just not you-The-Body-you. It's the divine essence that manifested as your body, which isn't substantially different from the divine essence that manifests as any given other thing. That divine essence is what generates all thoughts and consciousness, matter reflects those thoughts.
If "divine essence" puts anyone's backs up, you could rewrite that sentence as "The Force" (like Star Wars). It's an omnipresent invisible "stuff" that links everything in existence together and is responsible for everything. It wasn't put there by another entity, everything was put where it is by it. And it is you, and me, and everyone and everything we know, so on the one hand, it's not God, but on the other hand, it is, meaning this message is a memo from God (me) to theirself (you).
