The most telling and profound way of describing the evolution of the universe would undoubtedly be to trace the evolution of love.

God loves everyone in the world who doesn't love himself. Does God love God?

The world can no more have two summits than a circumference can have two centres.

Growing old is like being increasingly penalized for a crime you haven't committed.

The zest for life, which is the source of all passion and all insight, even divine, does not come to us from ourselves.... It is God who has to give us the impulse of wanting him.

It is not our heads or our bodies which we must bring together, but our hearts. . . . Humanity. . . is building its composite brain beneath our eyes. May it not be that tomorrow, through the logical and biological deepening of the movement drawing it together, it will find its heart, without which the ultimate wholeness of its power of unification can never be achieved?

The truth is, indeed, that love is the threshold of another universe.
