It really boils down to this: that all life is interrelated. We are all caught in an inescapable network of mutuality, tied to a single garment of destiny. Whatever affects one directly, affects all indirectly.
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.
Barnaby was what I call "heart smart." While other dogs accompanied me in our intellectual journeys and listened while ideas came in, Barnaby just walked and walked with me, looking at the river or the woods and feeling deep feelings. Rarely have I had a walking companion who could just be silent, not having to make a talking point or a barking commentary. With Barnaby, one barked in silence in which much of a more contemplative nature was communicated -- peace, simplicity, the glory of the natural world, the presence of God.
