The meaning of life
Suffering is meaningless in itself. The pain we encounter takes a hold of our lives. Pain changes us: there is a clear "before" and an "after".
And with that, the ways we viewed the world may suddenly become quite shaken. We struggle to make sense of things.
But humans will look for meaning, and when it seems gone, we will eventually restore meaning to our lives. We have to "relearn the world", as Robert Neimeyer, an American grief therapist and author puts it.*
Reinterpreting one's life is a common phenomenon after experiences of loss.
