Each person, no matter how old, has an important work to do. This good work not only accomplishes something needed in the world, but completes something in us. The work we do in the world, when it is true vocation, always corresponds in some mysterious way to the work that goes on within us.
To the degree that each of us is dedicated to wanting there to be peace in the world, then we have to take responsibility when our own hearts and minds harden and close. We have to be brave enough to soften what is rigid, to find the soft spot and play with it. We have to have that kind of courage and take that kind of responsibility. That's the true practice of peace.
