Be not anxious! Earthly possessions dazzle our eyes and delude us into thinking that they can provide security and freedom from anxiety. Yet all the time they are the very source of all anxiety. If our hearts are set on them, our reward is an anxiety whose burden is intolerable… When we seek for security in possessions we are trying to drive out care with care, and the net result is the precise opposite of our anticipations. The fetters which bind us to our possessions prove to be cares themselves.
