Several ideas pop into my head:
-You cannot drive out the darkness with darkness, only light can do that (pretty sure this is a quote from somewhere)
-sometimes the darkness makes the makes us appreciate the light
-having gone through the darkness, we can now show others the way
-In Star Wars, we often think of the Dark Side of the Force as bad. Conversely, the Light Side of the Jedi is thought to be good. However, I read somewhere that the darkness could actually be more representative of PASSION and the light could be more identified with PEACE and acceptance/tranquility. I wouldn’t discard either side, but rather both need to be used together in balance.
-If your life feels like a dark room with the lights off, once the light is turned on, it doesn’t matter how long the light has been flipped off. Instead, we should just focus on the fact that we’ve escaped and now live in the light. Too many times people tend to ruminate on their past and how terrible it was without being able to move forward and focus on what’s different. What you focus on is what expands, right? Where focus goes, energy flows (as Tony Robbins says)
-In the book “Relentless” by Tim Grover, he discusses how Cleaners (an elite level performer) taps into their darkness, the side of them that isn’t restricted or held back. Think of Dr. Jekyll and Mr. Hyde. One lives in the light with all the societal restrictions. One lives with raw, animalistic instincts, not bound by any rules. One can easily see which one is more powerful given their different positions. High level performers can tap into the “zone” by utilizing their dark side and achieving a state of flow and focus. It’s a really fascinating concept. The most prominent Cleaner he discusses is Michael Jordan, the legend.
