Spirituality is that quality of being that expresses the bonding of all living and non-living things into an evolutionary unity.
Perhaps the important matter is that we are who we are and where we are by a maze of reasons unknown to us. Our work is to make our way through our situation with faith and courage and whatever else it takes... In the end we are not only a mystery to one another but even to ourselves. The task is to live the mystery rather than unravel it.
