…there is also an underlying, less specific fear - what some might call an ontological or existential anxiety - that shrouds our days and seeps into our dreams. We feel empty and seek meaning. We feel empty and seek meaning. We yearn and know not what we yearn for. There is a black hole at the center of our understanding that engulfs and crushes our every attempt to explore it. Something is missing.
