Sometimes the darkness beyond is not glorious at all, it truly is an absolute absence of light. A clawing, needy tar that pulls you down. You drown but you don't. It turns you to lead so you sink faster in its viscous embrace. It robs you of hope and even the memory of hope. It makes you think you've always felt like this, and there's no place to go but down, where it slowly, ravenously digests your will, distilling it into the ebony crude of nightmares. And you know the darkness beyond despair, just as intimately as you know the soaring heights. Because in this and all universes, there is balance. You can't have the one without facing the other. And sometimes you think you can take it because the joy is worth the despair, and sometimes you know you can't take it and how did you ever think you could? And there is the dance; strength and weakness, confidence and desolation.
