"Blessed are they that mourn, for they shall be comforted." All things are given to those who demand, and they only deserve them, and they only can enjoy them. The infant cries when he is hungry and to him the food is given, and it is then that he enjoys it most. So it is with the lovers of God, with the seekers of Truth; when their desire becomes so deep that it makes them mourn, it is then that they are comforted.
