Darkness was created with purpose, just as light. It is only the human mind that has confused the two and wreaked havoc in the world.
In this murky swamp of confusion, darkness becomes evil, for it entraps the light. When we tug to fissure their bond, an iron resistance opposes us.
But that is our mission; it was for this healing that we were given the inner wisdom, the Torah. So with every progress of wisdom and each act of beauty, we loosen that bond.
In the final release, a burst of energy shakes the cosmos.
