If you've been around long enough, and you pay attention, some things become clear...
Any day is anything can happen day. Anything happens all the time. Good things. Bad things. I suppose it's all in the eye of the beholder.
And good things happen to bad people. And bad things happen to good people. And there is no justice on the human realm. And when human beings try to enact "justice," things often end up even more unjust. Maybe there's some cosmic, karmic justice, but as beings in this grand edifice we are too little and too dim to make it out. We don't get to make those kinds of judgements. And my guess, Judgement Day is just another thing like the Tooth Fairy. Sounds good, but probably not real.
Is there a plan? Is there fate? Is it all luck and probability? We don't know, and probably never will. We have developed some nifty tools: math, physics, economics, philosophy, religion, science, psychology, art; they are all ways to try to make sense of this constant stream of never-ending, always confounding, moments. Nifty but inadequate to contain what we want to contain.
We will make predictions and plans, and sometimes they will work out, and sometimes not. You would hope it would kind of even out, but it doesn't work that way. You can have a good streak, a bad streak, and those streaks can define your life.
And we are all going to live through events and times that are unbearable. For sure. We will witness the death of loved ones, we will endure broken hearts and broken dreams, we will lose things most precious to us. Some of us will also experience incredible love and acceptance, and have great moments of insight and transcendence. Again it's all sort of a crap shoot. If you are lucky maybe the good and bad can kind of even out, but that is not a given.
What to do? Carry on. As best we can. Lean to the light. Even if we don't see the light. Sitting in darkness, in silence, we can imagine a light. Sometimes the imagining is all we get.
