The poet, the writer ... is sharing their thoughts and feelings with the universe on another level. Revealing their greatest vulnerabilities as some sort of cathartic alm towards understanding and empathy, or there for the grace of God go I. Perhaps a confessional place where they commune with themselves and readers will acknowledge that similar darkness and light within themselves and not feel so different, or alone. This is the way of all writing, whether it is about joy, or despair.
