Hi MobiusX, welcome to the forum
I'm sure others will give you a better answer, but these are my own thoughts on your question, and anyone, please feel free to correct me if I'm wrong.
I think as individuals, we can be separated into two halves, the physical self and the spiritual self, both combine to make us who we are today. Thoughts and actions come from the brain, or the physical self, and feelings and emotions come from the heart, not the organ, but the heart of oneself, or the soul. I also believe that memories are contained both within the soul and the brain, because the act of remembering
(from the brain) various events throughout one's life can often evoke strong feeling or emotion
(from the heart, or soul)
When the physical body dies, the soul, or consciousness, is no longer tied to that vessel and returns to its source where the recent life is reviewed and the next life is determined, then the process begins all over again. The soul inhabits a new body, bringing with it the learning gained from previous lives. Without a soul, the physical body would be just an 'automaton'.
I hope I've understood your question properly, and like I said, others will probably add to my reply and hopefully correct me if I've missed anything
Chris
