It becomes increasingly clear that humans have a common origin and a common destiny with every other component of the Earth community. We live on the same planet. We breathe the same air. We drink the same water. We share the same sunlight. We are nourished by the same soil. In all these ways we share in a common spiritual mode of being as well as in a common physical sustenance.
