Amen. A bridge between our soul and the physical world. Yet the bible provides that answer. its the mind.
The mind is just a memory operation .the bible never mentions the brain because there is no brain. Its not that complicated. Its just a soul/heart working with a memory which itself is connected to the body.
This is why our senses are just sent into the skull and only land in the memory. Then our soul reads them, or reads them while asleep called dreaming.
This is why optical illusions work. They are not illusions but revealations that we don’t have any connection with the world outside the skull. WE only get a recording/memory of it and read that including some editing in the process.
This is also what happened to Jesus. When born we was stuck to a human memory/mind. so he couldn’t remember all the God stuff he knew. thats why the bible says Jesus grew in wisdom as a kid. This would not happen if he remembered all he knew before.
