I have given no definition of love. This is impossible, because there is no higher principle by which it could be defined. It is life itself in its actual unity. The forms and structures in which love embodies itself are the forms and structures in which love overcomes its self-destructive forces.

The most intimate motions within the depths of our souls are not completely our own. For they belong also to our friends, to humankind, to the universe, and the Ground of all being, the aim of our life.
