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.
From God is in the Manger: Reflections on Advent and Christmas, Dietrich Bonhoeffer
