On a steep and
rocky path [in Africa] I encountered a small girl who carried on her back her
little brother.  "My child," I said to her, "you carry a heavy burden."  She
looked at me and said: "I carry not a heavy burden.  I carry my brother!"  I
remained speechless.  The words of this child sank deep into my heart.  When
people’s troubles seem to weigh me down to a point that I nearly lose heart, the
words of the child come back to me: "I carry not a heavy burden.  I carry my
brother!"
