Sincerity is the foundation of the spiritual life.

I see in him (Dr. Max Gerson) one of the most eminent medical geniuses in the history of medicine...he was greatly impeded by adverse political conditions.

I have given up the ambition to be a great scholar. I want to be more- simply a human. . . . We are not true humans, but beings who live by a civilization inherited from the past, that keeps us hostage, that confines us. No freedom of movement. Nothing. Everything in us is killed by our calculations for our future, by our social position and cast. You see, I am not happy-yet I am happy. I suffer, but that is part of life. I live, I don't care about my existence, and that is the beginning of wisdom.

I don't know what your destiny will be, but one thing I know: the only ones among you who will be really happy are those who will have sought and found how to serve.

It is through the idealism of youth that man catches sight of truth, and in that idealism he possesses a wealth which he must never exchange for anything else.

The the question whether I am a pessimist or an optimist, I answer that my knowledge is pessimistic, but my willing and hope are optimistic.

The only way out of today's misery is for people to become worthy of each other's trust.
