I believe in the Holy Ghost who resides within each of us. For most, this ghost is catatonic. Many humans refuse to acknowledge its existence.
But this ghost (soul, spirit, true self, angel, child of God) is the only permanent part of us.
I believe there are spirits who have turned to the dark side. Most of us have, to a greater or lesser degree. By our great fall, we have pulled the blindfold of ego over our spiritual eyes which caused our Long Sleep. Only by subduing ego can we ever hope to reawaken the true self, within. Our focus needs to be on helping others through love and generosity.
If ever anything bad happens to us, we need to be entirely grateful for it, and to take 100% responsibility for it. Only in this manner can we ever hope to let ego die. Only with such fearless responsibility can we waive our supposed "right" to blame. Only with this can we ever entirely give up being victim.
With our reawakening, we become the Holy Ghost who has a human body. And by consciousness residing in spirit instead of flesh, we gain everlasting life.
