Once when I was sitting in the presence of Shakr Ali Ebah Ganj, a very great mystic, I asked him whether he knew the Sufis of Afghanistan. He had travelled very far. He said: "They are Chishtis, but they do not like music." This astonished me very much, because the Chishtis have a great devotion for music. He explained that the cold climate of Afghanistan does not allow music to have its effect.
