False hope is self destructive

The death rate in the week between Christmas, 1944, and New Year's, 1945, increased in camp beyond all previous experience. [...] the explanation for this increase did not lie in the harder working conditions out the deterioration of our food supplies or a change of weather or new epidemics. It was simply that the majority of the prisoners had lived in the naive hope that they would be home again by Christmas. As the time drew near and there was no encouraging news, the prisoners lost courage and disappointment overcame them. This has a dangerous influence on their powers of resistance and a great number of them died.

Losing hope is the path to personal destruction

The prisoner who had lost faith in the future - his future - was doomed. With his loss of belief in the future, he also lost his spiritual hold; he let himself decline and became subject to mental and physical decay. Usually this happened quite suddenly, in the form of a crisis, the symptoms of which were familiar to the experienced camp inmate.

Stoic influences

We who lived in concentration camps can remember the men who walked through the huts comforting others, giving away their last piece of bread. They may have been few in number, but they offer sufficient proof that everything can be taken from a man but one thing: the last of the human freedoms - to choose one's attitude in any given set of circumstances, to choose one's own way.

Love is the ultimate Truth

A thought transfixed me: for the first time in my life I saw the truth as it is set into songs by so many poets, proclaim as the final wisdom by so many thinkers. The truth - that love is the ultimate and the highest goal to which man can aspire. Then I grasped the meaning of the greatest secret that human poetry and human thought and belief have to impart: The salvation of man is through love and in love. I understood how a man who has nothing left in this world still may know bliss, be it only for a brief moment, in the contemplation of his beloved. In a position of utter desolation, when man cannot express himself in positive action, when his only achievement may consist in enduring his sufferings in the right way - an honorable way - in such a position man can, through loving contemplation of the image he carries of his beloved, achieve fulfillment. For the first time in my life I was able to understand the meaning of the words, "The angels are lost in perpetual contemporary of an infinite glory."

Love goes very far beyond the physical person of the beloved. It finds its deepest meaning in his spiritual being, his inner self. Whether or not he is actually present, whether or not he is still alive at all, ceases somehow to be of importance.
