When a person sees only the surface, it appears as if one has an easy life and another has to toil all day; as if one has a gay life and another is miserable. But that is the outside. When we look deeply into life, in some way or another, whether a person looks cheerful or sad, some captivity is always hidden there. We do not know. In order to understand their life's situation it is not enough to cast a glance at people from the outside. We only see the prisoners; if we saw the prisons we would be shocked.
