There were so many great questions featured.  Regrettably, the question had to be edited down.  I hope you are able to resubmit some, if not all of them, in the future.  I think that the messages from Wiesel's book are significant and powerful.  One of the most dominant messages is the need to remember and "never forget."  Wiesel's work speaks to the need to recall painful memories as part of one's own psychological condition.  For Wiesel, the need to reflect and bring these memories out in the collective consciousness of the reader helps to emphasize the need for victims of violence to speak their experiences.  Wiesel's pain and the need to share it is a message that resonates on both political and personal levels.  This message is one that makes the work one that makes the Holocaust something that cannot afford to be dismissed and one that can never fully be put away.

Another message that arises from the work is a study about the nature of religious faith.  In reading Wiesel's discussion of faith in the work, one recognizes that a central message  is to open a discussion about the nature of religious faith.  The reader is left to critically examine their own condition in the midst of Wiesel detailing his and the spiritual experiences of those around him in his narrative.  I think that this becomes one of the most powerful and compelling messages of the work.  Combined with the need to remember and not forget or defer the pain of the past, the discussion of spiritual identity become the most critical messages arising from the work.
