We are born to make manifest the Glory of God that is within us. It is not just in some of us; it's in everyone. And as we let our own light shine, we unconsciously give other people permission to do the same. As we are liberated from our own fear, our presence automatically liberates others.
Nothing is more difficult than prayer. In all other tasks of spiritual life, however exacting, one can sometimes rest, but there is no rest in prayer, up to the end of one's life.
