The most satisfying thing in life is to have been able to give a large part of one's self to others.

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

A breeze passes in the night. When did it spring up? Whence does it come? Whither is it going? No man knows.

We are collaborators in creation.

Joy is the sheer evidence of God.
