I really believe that all of us have a lot of darkness in our souls. Anger, rage, fear, sadness. I don't think that's only reserved for people who have horrible upbringings. I think it really exists and is part of the human condition. I think in the course of your life you figure out ways to deal with that.
There is a wide, yawning black infinity. In every direction, the extension is endless; the sensation of depth is overwhelming. And the darkness is immortal. Where light exists, it is pure, blazing, fierce; but light exists almost nowhere, and the blackness itself is also pure and blazing and fierce.
I guess darkness serves a purpose: to show us that there is redemption through chaos. I believe in that. I think that's the basis of Greek mythology.
Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that.
