Treachery is everywhere
The world is a treacherous place. A Dark Adept comes to know that treachery is empowering. All the contradictions in life. So many dissonant situations, conversations, events, people, beliefs...
“That’s why you must always remain receptive to the currents of the Dark Side, because no matter how nimble you are, or think you are, the Force will show you no pity.”
~Darth Plagueis
Treachery can be empowering in much the same way as nihilism. If, in the grand scheme of things, nothing matters, that frees you up to decide what matters: what do you feel like doing? The same applies with treachery: that’s right, maybe you can’t trust people, ideas, religions, or any of that, maybe you can’t trust any stability that your words, beliefs, relationships, or anything else might seem to have. There it is, now deal with it. With awareness of it, what’s the excuse? You didn’t expect that to be a lie? People lie. You thought you could depend on your buddy for a ride since he rarely lets you down? Maybe something came up.
Lies aren’t always meant to be malicious, or even intentional, but they still happen. You’ll still encounter them. Your friend might’ve intended to give you a ride, but maybe his wife was in an accident and he had to go to the hospital to see her. Blame who you want, but sometimes the footing you were depending on just slides right out from under you. Treachery is like a storm, it doesn’t have to seek you out, it’s just there and if it throws a branch into your windshield or drops a tree on your house, you’ll still have to deal with that shit. Be mad, surprised, etc… whatever the situation inspires. But handle it.
Do whatever it is you do, do it well, and know that everything is treacherous. If, instead of exploiting it, you would prefer to use it as an excuse for your failures, it's not any fault of this treacherous world. It's yours.
