Yes, well, when it comes down to it, I go with "mystery." Huge portions of my life are unexplained & unknown. Especially to me.
I have spent much of my time on earth trying to figure things out. And it slowly dawned on me that the most important things in our lives or at least my life, are actually pretty "unfigure-out-able."
There were times in my life when this realization was a bit disappointing. But now, not so much. I am on the search for "wisdom" (or - wiz-dom!) But there are no great expectations. I am not unhappy with the mysterious nature of life.
