What happens is that you discover you're carrying so much weight that 90 percent of what you thought yesterday you are thinking about today and will think about again tomorrow. Your mind doesn't change because you are carrying too large a load. So the mind is caught. It's seized by its own structures. It can't consider different ways of thinking or doing or being or relating. It's all you can do with your psychic energy to keep pulling yourself along with this huge bag that you are dragging behind you.
