Albert Camus penned an exploration of the absurdity of life titled The Myth of Sisyphus. In it, Camus examined the essential absurdity of life (that we look forward to tomorrow even though tomorrow brings us closer to death).
One of the 4 chapters of the book covered the Greek myth of Sisyphus who was consigned to punishment in the underworld of rolling a boulder up a hill until, right before he reached the top, it rolled back down. Forcing him into a perpetual punishment of never completing his hellish task.
Camus essentially argued that, despite the unceasing toil, Sisyphus would actually be contented because he recognizes the absurdity of his fate and is thus able to reach a state of acceptance. This is similar to the theme found in many religions in which the acceptance of death is the precursor to satisfaction in that it removes all vanities so that one can focus on the joys of life.
We each need our mindless task, a continuing struggle that makes us confront our vanities and fears. This is not a call to sink into negativity but, rather, a call to action. Mine is kendo, specifically suburi and hayasuburi. In my daily practice each swing is done fully with as much as focus as I can muster until I can almost smell the wood of the shinai or bokken and the sound of the strike.
“The struggle itself towards the heights is enough to fill a man’s heart. One must imagine Sisyphus happy.”
