If I have any expertise, it is in the realm of spiritual darkness: fear of the unknown, familiarity with divine absence, mistrust of conventional wisdom, suspicion of religious comforters, keen awareness of the limits of all language about God and at the same time shame over my inability to speak of God without a thousand qualifiers, doubt about the health of my soul, and barely suppressed contempt for those who have no such qualms. These are the areas of my proficiency.
