Until two hands of an astral body harmonize and merge there is heaven & hell.
As if a single consciousness must fluctuate between wake & dream of a physical body, at the time of death stronger pole takes over.
If negative pole is more powerful, I AM falls into its own fear and darkness, if positive pole is stronger enters light dimension, but until spiritual body stays polarized must reincarnate again.
Father symbolizes light and mother darkness, and they give birth to a child, but alter by evolution of consciousness. 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 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 self and control the mind, I AM becoming eternal consciousness.
