Imagine that you are standing on a beach, looking at a sand dune. At first glance, the sand dune may seem like a solid, permanent object. But as you begin to examine it more closely, you will realize that it is not a static, permanent object. Rather, the sand dune is constantly changing and shifting, dependent on various factors and conditions for its existence.

For instance, the sand dune is dependent on the wind for its formation and maintenance. It is also composed of individual grains of sand, which are themselves constantly moving and shifting due to various environmental factors. If you were to break down the sand dune into its constituent components, you would find that it has no inherent self-nature or essence. It is simply an ever-changing collection of sand particles, dependent on various conditions for its existence.

This recognition of emptiness can help us to realize the impermanence and interdependence of all phenomena. By seeing the sand dune as a constantly shifting collection of components rather than as a fixed, permanent object, we can begin to see the world in a new way. This can lead to a greater sense of wisdom, compassion, and freedom in our lives.
