Challenging the meaning of life is the truest expression of the state of being human.

Happiness cannot be attained by wanting to be happy - it must come as the unintended consequence of working for a goal greater than oneself.

Pain from problems and disappointments, etc., is inevitable in life, but suffering is a choice determined by whether you choose to compare your experience and pain to something better and therefore feel unlucky and bitter or to something worse and therefore feel lucky and grateful!

A life of short duration...could be so rich in joy and love that it could contain more meaning than a life lasting eighty years.

A human being is not one thing among others; things determine each other, but man is ultimately self-determining. What he becomes - within the limits of endowment and environment- he has made out of himself. In the concentration camps, for example, in this living laboratory and on this testing ground, we watched and witnessed some of our comrades behave like swine while others behaved like saints. Man has both potentialities within himself; which one is actualized depends on decisions but not on conditions.

To draw an analogy: a man's suffering is similar to the behavior of a gas. If a certain quantity of gas is pumped into an empty chamber, it will fill the chamber completely and evenly, no matter how big the chamber. Thus suffering completely fills the human soul and conscious mind, no matter whether the suffering is great or little. Therefore the "size" of human suffering is absolutely relative.

Man is not fully conditioned and determined but rather determines himself whether he gives in to conditions or stands up to them.
