We are all searching for a common cure to heal the suffering between us.
I have not found one either, but I know of something that may help —

Come, sit.

Lessen the distance between your wars.
Look into the eyes of whom you’ve made a stranger, an enemy.

Sit still.
Until all that moves is the rise and fall of shared breath.

Hold your gaze.
Until the armour of your pain drops to the ground.

Stay.
Until love breaks the surface. 

Stay.
Until your eyes find the soul of the other.

Stay.
Until you see a part of yourself reflected back.
