It is in this that there is the mystery of the spiritual hierarchy; it is only the expansion of heart. Do we not see this in our everyday life? There is one person who says, "Yes, I can love one person, whom I love; but then I cannot stand the others." It is only the limitation of the heart. There is another person who says, "Yes, I can love my friends; those with whom I feel at home and feel a contact; but not the strangers; I cannot love them; before them I am closed." And he really is closed before strangers. He may be a loving person, but in the presence of strangers his love is closed.
