God grant ... that he may learn to understand in time, that whoso is minded to do as he himself wills will soon enough see the day when he will find he has done that which he had never willed.

Her heart felt as if it were breaking in her breast, bleeding and bleeding, young and fierce. From grief over the warm and ardent love which she had lost and still secretly mourned; from anguished joy over the pale, luminous love which drew her to the farthest boundaries of life on this earth. Through the great darkness that would come, she saw the gleam of another, gentler sun, and she sensed the fragrance of the herbs in the garden at world's end.

All those wasted and squandered years when I did nothing but go around looking inside myself until I ended up alone even though I was surrounded by people. But I paid attention only to what was happenstance about them - not their true selves.

It seems to her [Saint Catherine of Siena] that the devil has this world in his power, not by his own will, for he is powerless, but through our help because we obey him. The evil aroma rising from the ... wars which are waged by Christians against Christians, are the same as war against God. ... Peace, peace, for the sake of the love of the crucified Christ, and not war; that is the only solution.
