“I have had the experience over and over again that the quieter it is around me, the clearer do I feel the connection to you. It is as though in solitude the soul develops senses which we hardly know in everyday life. Therefore I have not felt lonely or abandoned for one moment. You, the parents, all of you, the friends and students of mine at the front, all are constantly present to me…. Therefore you must not think me unhappy. What is happiness and unhappiness? It depends so little on the circumstances; it depends really only on that which happens inside a person.8 Bonhoeffer’s final Christmastime letter to fiancée Maria von Wedemeyer, December 19, 1944”
