We amass material things for the same reason that we eat - to satisfy a craving. Buying on impulse and eating and drinking to excess are attempts to alleviate stress. From observing my clients, I have noticed that when they discard excess clothing, their tummies tend to slim down, when they discard books and documents, their minds become clearer, when they reduce the number of cosmetics and tidy up the area around the sink and bath, their complexion tends to become clear and their skin smooth. -p226
