I have treated many hundreds of patients. Among those in the second half of life - that is to say, over 35 - there has not been one whose problem in the last resort was not that of finding a religious outlook on life. It is safe to say that every one of them fell ill because he had lost that which the living religions of every age have given their followers, and none of them has really been healed who did not regain his religious outlook.

Where wisdom reigns, there is no conflict between thinking and feeling.

Even a happy life cannot be without a measure of darkness, and the word happy would lose its meaning if it were not balanced by sadness. It is far better take things as they come along with patience and equanimity.

As far as we can discern, the sole purpose of human existence is to kindle a light of meaning in the darkness of mere being.

Everything that irritates us about others can lead us to an understanding of ourselves.
