It is a recurrent theme in human history,  and in the different wisdom traditions on days like Good Friday, that the places where we are hurt are often the places where we grow the most. Thus the places of darkness are difficult and fruitful at the same time:

Life may be brimming over with experiences,

but somewhere, deep inside,

all of us carry a vast and fruitful loneliness wherever we go.
