Darkness is the absence of light (God) and there can only be a darkness if light is SHUT OUT, which you do by entering into some kind of private, secret world, where you do not 100% fully share things openly. Indeed, coming into the physical world is an attempt to enter into a secret, private world, where God's light is absent - a world of darkness and despair.
If you are not fully 'open', like the shutter on a camera, light cannot get all the way in. If the shutter is closed, you will have a picture of darkness. When you 'shut down', become closed, withdraw, hide, go into secret fantasy land, conceal, deny, resist, attack, or in any way enter into EGO, you are shutting out the light.
Things that you KEEP in the dark, remain seemingly unhealable because you are not allowing them to gain light exposure. Exposure to light shows them for what they are and dismisses them, effectively revealing that they only existed IN the dark and do not really exist IN the light at all.
Therefore, everything that you do in the dark, or in secret, or which you keep buried, or do not want to admit to, ONLY EXISTS so long as you KEEP it in the dark, because it is MADE FROM darkness itself. All illusions are made from darkness. They are not made from light.
So as you expose yourself to God/light/love, these dark things must be exposed to the light and seen IN the light, and since they are not made OF light they do not exist in the light, so when you look IN the light for them you will not find them, because they will have DISAPPEARED. Light shines away darkness because darkness is only the absence of light, not a real thing in itself. This is why shadows disappear when light illuminates the scene. This is why the darkness of night disappears when the sun comes up. Where does it go? It does not exist.
You can stay in the dark and keep your dark illusions and dark fantasies about how dark you are and how real the darkness is, OR, you can open up and expose yourself courageously to God, knowing that GOD DOES NOT ATTACK, and GOD LOVES YOU UNCONDITIONALLY, and ALLOW the light to heal you of this darkness. Love replaces darkness with itself, and you are NOT held accountable for being dark, because you are MADE OF LIGHT.
Darkness is illusion. Light is reality. In truth you are innocent and holy, but if you don't allow yourself to step into the light, you will believe you are sinful and guilty. Only in the dark, where you cannot even see properly, could you think you are sinful and guilty. Only in the light, where you can finally SEE, can you be ABLE to recognize that you are only pure and innocent.
"I cannot see in darkness but in light"
"I am not an illusion but a reality"
