It is a story about you.
It begins with a boy who lost his shadow.
This is a parallelism to Christ’s warning about one evil spirit and the clean house.
The most unruly ruler believes rules get rid of unruliness. But getting rid of unruliness is impossible because ruliness and unruliness are like states of matter. They just are.
Unruliness is dependent on ruliness, just as ruliness can not exist without unruliness.
In the same way, it is wrong to say cleaning gets rid of dirt. Of course it doesn’t. In fact, it is just as easy to say cleaning makes more room for dirt.
Cleanliness does not get rid of dirtiness.
A set of external rules for right behavior does not get rid of wrong behavior. It does not do anything because it is just a concept. And a concept cannot do anything about something as real as evil. Or said another way, morality that has a motive to accomplish something, accomplishes nothing. It can neither create good nor destroy evil—if anything, it does the opposite. Rather, good and evil simply exist, in the same way high and low do—one only exists in relation to the other. The rules the ego learns to follow are not primary education. They are an epiphenomenon of existence. It is why it was essential that the Ten Commandments were inscribed by the hand of God Himself—not man. Just as it was essential that Jesus walk into the wilderness and stand in front of the mirror to face his brother—his dark self—Satan—not because he was told to do it, but because it was foretold by existence itself. At the very beginning, the moment man awoke to self-consciousness in the garden, exactly then, he beheld a core of poisonous fruit in his palm. From the tree that should not have been touched because it made the knowledge of God become the knowledge of man. The moment man ingested desire--wanting--value—he blinded himself to the only cure: to un-desire, un-knowing, un-holding.
The villain never really dies. He always comes back. By not speaking his name Voldemort only comes back with more horcruxes. So something else must be done with evil besides pretending its not there or it multiplies seven-fold. Somehow simply knowing of its close quarters in our heart, saps evil its power.
It is learning to live with dirt—incorporate it—accept it—in your life that makes a home livable.
An Evil spirit does not exist without the good. And good can not be understood without evil. It is in seeing this and incorporating this, that halts the multiplication of evil within.
