Metta Sutta

           Do not be satisfied with the mere recitation of the

          "Metta Sutta" but strive to know its meaning with a view to

          practicing it and to make it suffuse your being. That is the most

          essential fact. Meditation does not mean merely to think about it,

          but to practice it in your daily life.
