How did Elie Wiesel deal with the memories of the Holocaust?

"From the depths of the mirror, a corpse was contemplating me. The look in his eyes as he gazed at m has never left me." pg. 115

After the liberation of the Jews became a journalist, but he vowed never to speak or write of his experiences in the concentration camps. He went to study journalism in France, where he met Francois Mauriac, a French writer. Mauriac then convinced Elie to break his silence, and speak of his time in Auschwitz. Elie then made it his job to use what had happened to him in a positive way; to inform people all around the world and make sure nothing like the Holocaust would ever happen again. He became chairman of the President's Commission on the Holocaust, planned many memorials to the murdered Jews, and wrote over 30 books speaking about Jews, the holocaust, and genocide in general.
