"We can only obey our own polarity," stated American Transcendentalist Ralph Waldo Emerson, "'Tis fine for us to speculate and elect our course, if we must accept an irresistible dictation."  So Emerson observed in "Fate," an essay he published in 1860.  Like all of us, Emerson struggled with the often frustrating balance between what we want to do with what actually happens.  Though we all make plans, though we all develop life visions, big or small, we all know that, as many have said, "Stuff happens."  We never know.
     

     The ancient Greeks envisioned three spinster sisters who lived in a cave far away from all human habitation who rolled out a length of thread for every human being then, in seemingly arbitrary fashion, snipped it.  The point at which they snipped the thread marked the end of that person's life.  Sometimes the sisters rolled out the thread for some distance, say for the playwright Sophocles, who lived to be ninety.  Other times the sisters snipped the thread very soon after rolling it out, perhaps for the Spartan babies who were considered deformed at birth and promptly discarded.  Either way, neither gods nor humans could undo the sisters's decision.
     Although most of us today do not believe in these spinster sisters, we nonetheless wrestle with what appears to be the rather arbitrary and uncontrollable nature of existence.  We all know about people who appear to have done everything they can to ensure good health, then abruptly drop dead of a heart attack, as did a 64 old master's level runner in Michigan (I learned of this from my brother) a couple of years ago.  And we are all aware of people who seem as if they will die young, then live to a ripe old age, including any number of rock musicians who, despite having abused their bodies greatly, keep going.  Many people use Rolling Stones guitarist Keith Richards as one example of this.
     Regardless, we all must come to grips with the uncertainty of existence.  It's a delicate balance.  Even if we accord ultimate sovereignty to God rather than the simple randomness of reality, we nonetheless stand before the same issue:  we walk in profound mystery.
