Life is always changing. Cling on to things as we may, inevitably change occurs. In Buddhism it is called Impermanence, and understanding it is a way to reduce suffering. Simply, we must accept that things change and be willing accept it. The more we try to hold on and capture relationships, glory, wealth, beauty etc., we find that when they are gone, change, or no longer ideal this creates pain and yearning. Instead, it is better to understand that things come and go, life is constantly in a state a flux, and it is better to savor each moment rather than trying to capture it. The Outer Banks of North Carolina is a place of constant visible change and demonstrates the temporary state of things.
The Outer Banks are a geological case study in impermanence. The forces of erosion do not take decades or years to observe. In the course of hours, on a windy day, sands can cover roads, dunes shift, and three feet of beach is swept away. During large storm events the islands will reshape dramatically. Land is constantly being taken away from one location and redistributed else where, as the islands steadily march south and westward.
