Have you read Vegetarian by South Korean writer Han Kang?  One of several highly unusual books Kang has published, Vegetarian, although some of its imagery may strike one as dark and macabre, is worth reading.  It tells the story of a woman, a woman who to this point had been living a rather ordinary life, doing what most married South Korean women do, when she had a dream.  This was no run of the mill dream.  It was a nightmare.  Though I will not detail its bloody imagery here, what she dreamed so moved her that, upon waking, this woman resolved to forswear eating any and all meat. Forevermore, she would be a vegetarian.
     As time went on, the woman clung fiercely to her intention.  Even at the cost of not eating, she steadfastly refused to eat meat.  She began to lose weight, and was soon barely a stick of a human being.  But she would not stop.  Frustrated and crestfallen, her husband did not know what to do.  He could not understand his wife's obstinacy. Eventually, he had an affair and the marriage fell irretrievably apart.
     So what's the point?  Though Kang weaves many motifs through the novel, she seems to keep returning to one:  we rarely do not understand ourselves or each other in full.  Did this woman grasp the implications of everything she was doing?  Did her husband comprehend the full extent of his--and her--actions?  Did either of them understand the other in the first place?
     Toward the end of the story, we read some words a friend of the woman posed to her. "You see," she said, "it was just a dream.  We have to wake up sometime."
     Maybe she did.  Maybe we're all in a dream.  However, it's unlikely:  we live in a real world.  Yet how we respond to this world is another story.  If reality is true, which it is, and if we are more than materiality, which we are, then however many dreams we have and however they impact us, they will do so in people who are fundamentally spiritual beings.
     And although spirituality can seem like a dream, however odd it may appear to be, it is not.  It's not bloody, it's not reactive.  It's the most logical way to frame existence.
     As Kang points out, as we rarely understand, apart from doubt and faith, everything about ourselves and each other, so we rarely understand, apart from doubt and faith, God.
     In this is the greatest mystery--and truth--of all.
