The finer people go to see the tragedy where they are moved and shed a few tears. The ordinary people go to the moving picture where they laugh. The heart finds a joy in feeling, in sorrow. It feels that it is used, and in that there is a happiness. The Sufi trains the heart in feeling. There are assemblies among them where qawl is sung and played, the music of devotion and praise, the music that arouses feeling, the feeling of devotion, of sorrow, of repentance: to think how foolish we are, how stupid we are, how many mistakes we make. Every feeling is practiced. When the heart is made capable of feeling, it can feel the sorrow and joy of others. Every thing touches it, every little sign of mercy, every feeling of admiration. In this there is happiness.
