Be sure to strengthen your faith, and receive the protection of Shakyamuni, Many Treasures, and the Buddhas of the ten directions. Exert yourself in the two ways of practice and study. Without practice and study, there can be no Buddhism. You must not only persevere yourself; you must also teach others. Both practice and study arise from faith. Teach others to the best of your ability, even if it is only a single sentence or phrase.
