'Spiritual joys, on the other hand, are a matter of indifference to us when we do not possess them, but once we begin to experience them, we desire them.... When our souls are full of spiritual joy we long for more, since by tasting it we learn to desire it more eagerly. We cannot love what we do not possess, because we do not know its savor.'
St. Gregory the Great
