The belly button is a reminder of the closest and most important human relationship possible, the one between a mother and her prenatal child. It is a testament to the beauty of human life and the selfless sacrifice required to provide it.
Each of us once clung to life by an umbilical cord, receiving the constant supply of nutrients and oxygen we needed to survive and grow. Our belly buttons remind us that without another who came before us, we would not be. That life is a relay and we are only running a small distance in a never ending journey.
