Most of our conflicts and difficulties come from trying to deal with the spiritual and practical aspects of our life separately instead of realising them as parts of one whole. If our practical life is centred on our own interests, cluttered up by possessions, distracted by ambitions, passions, wants, and worries, beset by a sense of our own rights and importance, or anxieties for our own future, or longings for our own success, we need not expect that our spiritual life will be a contrast to all this. The soul’s house is not built on such a convenient plan: there are few soundproof partitions to it.

—Evelyn Underhill, The Spiritual Life
