Lightning
They say love is a thing of raw power, but so are storms. You stare at the sky and try by force of will to summon a cloud from over the hilltops. Love is that mystery. The force of its creation is beyond mortals.
Then as we go through our daily tasks, with minds full of minuscule matters, there can be a day when the forces of nature conspire and collide. The all powerful electrical storm crackles and strikes. A single lightning bolt splits and strikes two humans directly binding them forever through this lifetime and beyond.
That binding lasts through lifetimes. That intertwining of two souls does not fear the fading of time or the complexities of circumstances.
It is the union written about from the birth of humanity to this day. And, when it happens it needs to be honored, cherished, and exalted because both lightning and true love never strike twice.
