So, that portion of one’s Self, which he has disowned by claiming he is finite, becomes an intuitive perception of potential of unattained good, or unattained life, but nevertheless attainable through some path or other. So, while that one identifies himself three-dimensionally, he is constantly reminded, goaded, pushed by his Actual Oneness and Universality to give up his finite view as fact. This whole process has nothing to do with evil, error (as power) the dark forces, evil powers, or the devil. You could say it is purely mechanical, with no values associated with it.
Source of the perception of evil (devil, darkness, etc).
The natural evolution of life.
This is important: The infinity of our Being shines through the belief in death as intuitive perception of potential. We are constantly - goaded - to return to Truth.
