“The pain-body’s unhappiness is always clearly out of proportion to the apparent cause. In other words, it is an overreaction. This is how it is recognized., although not usually be the sufferer, the person possessed. Someone with as heavy pain-body easily finds reasons for being upset, angry, hurt, sad, or fearful.” Eckhart Tolle (from The Power of Now)
Given this criteria, we can see that the Pain-body is all around us. Everyone is held hostage by their buried pain. This maybe why we love Zombie movies, where the pain rises from the underground and walks around. The Zombie is a metaphor for our pain-body.
Why does the Pain-body rise to the surface of everyday life? It wants to be released from its hell. So it rises with the hope of release through your acceptance of it. But no, we resist it, fight it, flee from it, project it, and in everyday avoid it. It hurts! So the Zombie chases us, not to kill us but to get us to turn and look at it, you know, like Beauty and the Beast. Your Pain-body just wants you to kiss the frog and release the Prince from its curse.
