Once again, no evidence suggests that spirits exist. I don't know why you keep insisting they do, but you are making an entirely unsupported, entirely superstitious assertion.
If you want to keep doing that, please provide evidence.
Thoughts, feelings, and emotions arise in the brain, in processes that fairly well documented though incompletely understood.
Neurologists can even pinpoint where certain emotions like love, fear, etc originate in the brain, and can observe them turning off in people whose brains are damaged in particular ways.
The idea that some sort of "spirit" is needed to make this happen is not in any way supported by evidence. Again, "No need of this hypothesis" and "extraordinary claims require extraordinary evidence."
The idea that spirits, souls, ghosts -- or whatever you want to call them -- exist is an extraordinary claim supported by no evidence, let alone extraordinary evidence.
That claim is nothing but superstition.
