The soul is that little piece of God that God gave us at conception. For the first three months, the soul of the child is attached to the physical body of the mother, and after three months the soul enters the physical body of the baby. That soul inhabits us until physical death. After physical death, it goes back to the ethereal state, that is, the energy that exists. The soul of man is the only permanent one. She is eternal. Without it, we would not be alive, that is, we would not exist. Because of the soul, we have all the senses through which we can experience our current reality. Without a soul, we are just a physical skeleton made of flesh and blood, but without life.
