The eyes are the window to the soul.

This quote is now a well known proverb.  It traces back to the bible and even further back to Cicero.  Shakespeare and modern musicians take inspiration from this.  But what does it mean?  

I have no idea what my soul looks like, nor that of another.  I could perhaps tell you my aurora, but we're talking souls here.  Sometimes we walk down the street and we make eye contact for a brief moment.  Nothing.  Other times we look into another's eyes and are fixated in a strong hold.  It can be comforting, chilling, loving, tender, lust inducing ... there are a magnitude of emotions and feelings that can takeover you. On occasion you get lucky and this hold is so consuming you can't break contact.  You could gaze into those eyes forever.  Eyes intertwined, pupils aligned, every spec, dot, character emphasized.  There is everything you need to know in those eyes and lots of learning that could follow.  You're not reading their soul, their inner thoughts or makings.  What you can decipher is whether they are friend, lover, or foe.  All that without words.
