The state of sleep is a state of freedom in which man is not occupied with the manipulation of the outside world.

Love is an active power in man; a power which breaks through the walls which separate man from his fellow men, which unite him with others; love makes him overcome the sense of isolation and separateness, yet it permits him to be himself, to retain his integrity.

We are all equal in the sense that no man must mean - must be - the means for the purposes of another man; but each individual is an end in itself.

To love one person productively means to be related to his human core, to him as representing mankind. Love for one individual, in so far as it is divorced from love for man, can refer only to the superficial and to the accidental; of necessity it remains shallow.

To live is to be born every minute. Death occurs when birth stops.

In our enthusiasm to dominate nature and to produce more material good - goods - we have transformed means into ends.

Every act of irreverence for life, every act which neglects life, which is indifferent to and wastes life, is a step towards the love of death. This choice man must make at every minute. Never were the consequences of the wrong choice as total and as irreversible as they are today. Never was the warning of the Bible so urgent: 'I have put before you life and death, blessing and curse. Choose life, that you and your children may live.'
