Phisically we are a genetic piece of material, atoms, electrons, and soo on..

Inside our master organ (the brain) we have our personality, our inteligence,... But, behind the brain is our "spirit". (i dont believe that we are only a body)

What makes our body to connect to the spirit? How do we give orders to our brain? in wich part of our body is our soul?

What is our soul?
