Responsible people are beginning to realize that the earth is an awesome mystery, ultimately as fragile as we are ourselves. ...That being so, there is need to be sensitive to the earth, for the earth identifies with our own suffering, exploitation of the earth is exploitation of the human, elimination of the aesthetic splendors of the earth is the diminishment of all existence.
Every one of us has a "good work" to do in life, which accomplishes something needed in the world while completing something in us. When it is finished a new work emerges which will help us to make green a desert place, as well as to scale another mountain in ourselves. The work we do in the world, when it is a true vocation, always corresponds in some mysterious way to the work that goes on within us.
