That is not to suggest that we can live harmlessly, or strictly at our own expense; we depend upon other creatures and survive by their deaths. To live, we must daily break the body and shed the blood of Creation. When we do this knowingly, lovingly, skillfully, reverently, it is a sacrament. When we do it ignorantly, greedily, clumsily, destructively, it is a desecration. In such desecration we condemn ourselves to spiritual and moral loneliness, and others to want.
I used to think that the goal of life is to do equally well in the spheres of work and love. Now I know there is only one sphere. What matters is the way I treat everyone I encounter in the course of my days: my wife, my child, a friend, a colleague, a secretary, a textbook salesperson, a complaining student. What's important is to treat each one with courtesy, with respect...with love...We're all connected in a web of love.
