Until two hands of an astral body harmonize and merge there is heaven & hell.
As if a single consciousness must fluctuate between wake & dream TWO HALVES OF HIS OWN BODY, at the time of death stronger pole takes over.
If negative pole is more powerful, I AM fall into my own fear and darkness, if positive pole is stronger enter light dimension, but until spiritual body stays polarized must reincarnate again.
PARENTAL IMAGES ARE NOT ACCIDENTAL, they represent polar opposites within child's psyche, stronger it is more creative father and loving mother vs weakness and aggression resulting into depression and separation.
The waking consciousness represents light and dreaming is darkness as two hands of a single spiritual body and stronger her nervous system greater the light.
The second birth awakens male/female polarity, at first unconscious mother destroys father personality, after the father consciousness activates and evolves until they balance under a single will.
SO-CALLED HEAVEN & HELL REPRESENT STATES OF OUR OWN CONSCIOUSNESS, positive & negative, day & night, light & darkness, but as two hand harmonize to harness the mind, I AM becoming eternal consciousness.
