Push. Harder. Harder.
It's difficult. Against something else, it wouldn't have been a problem. You could use a beam blast them to smithereens. Pretend like there's nothing wrong, even as fear wells up in your stomach. Tell the world it's all alright, tell yourself it's all alright. Well it doesn't work here, because what's pushing back is part of you too, your doubts, your fears, your frustration. Ah yes, frustration. That's the kicker isn't? That dark energy, the curses, the negative emotions, they're part of you too, the side of you that you hide, well tried to hide anyway. Fear, rage, desperation, they're all negative emotions, emotions that will naturally arise when overcoming adversity, volatile, overwhelming, numbing. And sometimes, that just what you need to break through. The problem here is well, if you generate those emotions when you're overcoming something, what happens if their energy is precisely what you're trying to overcome?
Well, simply put, it doesn't fucking work. You dig your heels and force it? It just adds to the crushing pressure. Add more outward pressure and you get more inward pressure. It all comes back to this same tumultuous unstable equilibrium.
...An equilibrium huh? That's a thought. And no, not that zen balance of two internal forces bullshit. No no no, we're talking practical terms. A balance of two forces, collecting within them, an awful lot of energy. Like a star, radiation pressure and gravity, counteracting one another. What if you kept pushing, not trying to break through, but just to trap more energy inside this?
Your shield burns brighter and brighter, gold and purple roiling across the tumultuous surface, prominences of energy both positive and negative erupting, flaring and settling all across its surface. It's not exactly easy maintaining it, but you are maintaining it, this shifting barrier of energy born of your conviction. If you can meet with Triumph and Disaster eh? Well, you'll pass on Kipling's offer to become a man, but you'll happily take a shield outta this whole deal.
