The Soul after Death
152. What proof do we have of the individuality of the soul after death?
“Has spirit communication not provided the necessary proof? If you are not blind, you will see; if you are not deaf you will hear. A voice often speaks to you revealing the existence of a being outside yourself.”
People who think that the soul returns to the universal whole after death are wrong if they think that, it loses its individuality like a drop of water in the ocean. They are right if by universal whole they are referring to all incorporeal beings, of which each soul or spirit is a component.
