What do you think you are doing by infesting the whole world? Because I do it with one puny boat, I am called a pirate; because you do it with a grea… - Augustine of Hippo

It is not by change of place that we can come nearer to Him who is in every place, but by the cultivation of pure desires and virtuous habits.

"For I wondered that others, subject to death, did live, since
he whom I loved, as if he should never die, was dead; and I wondered
yet more that myself, who was to him a second self, could live, he
being dead. Well said one of his friend, "Thou half of my soul"; for
I felt that my soul and his soul were "one soul in two bodies": and
therefore was my life a horror to me, because I would not live halved.
And therefore perchance I feared to die, lest he whom I had much loved
should die wholly."
