The effect is even more exaggerated when people are placed in an natural environment, itself full of basic elements; Stone, Water, Earth, Plant Life. The very elements that nurture and sustain us in life and that over time we all will eventually become.
Over time the clay drys and cracks creating a symbolic road map of our own journey and the textures of our experiences in life. Eventually, as with everything the mud turns to dust unable to hold to the body any longer, it falls to the ground or is washed or blown away and like ourselves it will eventually integrate into something else within this world.
We as humans are relentless, we quest to evolve and prove that we are dominant over each other and the planet itself, we have forgotten who we are; our organic natural born selves. Yet with the simple act of reconnecting, we remind ourselves that still at heart, primitive beings and we essentially still function the same way we always have.
