Barnaby was like a mood, a fragrance of the harmonious inner life, permeating everything with which he came into contact. He knew sorrow and he knew joy, and he held them in a delicate balance of serenity and peace. He knew how to respond equally joyfully to an invitation to walk or talk or sit together, which seems to me to be a particular kind of training in grace -- a willingness to respond easily and happily to even the most modest adventure together. Perhaps it could be said that within his framework of being a dog, he lived life as a spiritual exercise.
All those magical, predestined, and irreplaceable people and places are not really that, not really the answer. Rather, we have to stay with the hunger of the question and from its energy fill the space with our own choices, and then with the new things which will be called forth from us in the unexpected poverty and limitation in which our necessarily imperfect choices necessarily situate us.
