First off, we need to define these.
My definitions are:
MIND - The physical brain. It is a part of the body and remains there, in life and death. It's the most important part of us, we can not live without it.
Unfortunately, this will all change in a decade.
BODY - That which you occupy while on earth. Everything that is connected to you. It is your earthly vessel here.
SOUL - This is what makes you, you!
This is, "inherently eternal."
It is what will go with you after you leave this life, at least that's what we are told.
This is what separates us from the other life forms on earth. They have their own instincts and we have control (or we are supposed to anyway) and can differentiate between right and wrong. Whether we choose to be right or not is another consideration.
