It is a peculiarity of man that he can only live by looking to the future.

What will it matter to him if he notices that he is growing old? Has he any reason to envy the young people whom he sees, or wax nostalgic over his own lost youth? What reasons has he to envy a young person? For the possibilities that a young person has, the future which is in store for him? "No, thank you," he will think. "Instead of possibilities, I have realities in my past, not only the reality of work done and love loved, but of sufferings bravely suffered. These sufferings are even the things of which I am most proud, though these things are things that cannot inspire envy."

Fundamentally, therefore, any man can, even under such circumstances, decide what shall become of him—mentally and spiritually. He may retain his human dignity even in a concentration camp.

And I quoted from Nietzsche: That which does not kill me, makes me stronger.

Consider a movie: it consists of thousands upon thousands of individual pictures, and each of them makes sense and carries a meaning, yet the meaning of the whole film cannot be seen before its last sequence is shown. However, we cannot understand the whole film without having first understood each of its components, each of the individual pictures. Isn't it the same with life? Doesn't the final meaning of life, too, reveal itself, it at all, only at its end, on the verge of death?

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.

The salvation of man is through love and in love.
