He sincerely hopes that your group will daily increase in number and gradually begin to radiate its light of guidance to the neighbouring regions. Before that stage is reached, however, you should exert all your efforts upon deepening your knowledge of the teachings and literature of the Cause. The Writings of Bahá'u'lláh and the Master are like vast seas, the deeper you go into them, the more priceless treasures you will find. And it is only after acquiring those treasures that we can hope to share them with others.
