You have asked me to speak about how to teach the Cause of God. I have spoken at length on this but I repeat that the teacher himself must be detached and devoted so that his breath may affect others. Whoever has taken a step in this field has succeeded. The doors of knowledge are opened before him, his eyes become seeing and he is assisted with the breaths of the Holy Spirit. He is guided himself and becomes the cause of guidance of others. Of course, a person sings a joyous song only when he himself is delighted and rapturous. Thus when one begins to guide others and adduces proofs, then his taste becomes sweeter and his heart more joyful. (Words of ‘Abdu’l-Baha, October 24, 1912, Oakland, California; Mahmud’s Diary)
