In the book, the Devil explains that his part in life is the negative energy that lives in the minds of people who fear him. He occupies one half of every atom of physical matter, in every unit of mental and physical energy. He is basically the negative portion of an atom.
On the opposite side, there is God. God controls the positive factors and all the natural laws throughout the universe. He is the positive side of the atom. God is the positive forces of the world, which includes love, faith, hope, and optimism. The Devil explains that his job is to lure as many people as possible over to the negative side by occupying the unused space of the human brain.
The Devil uses fear and other sorts of bribes or motives to subdue you to a point where you no longer think for yourself. And when you’re in that zone, you’ll be taken over by the law of compensation — meaning you will “reap what you sow.” That’s why it’s important to understand that everything you do and everything around you is energy.
