Once when we noticed that every night a group of French students were coming to hear the speech of the Imam, we asked them through one of the brethren who spoke French to ask them whether they knew Farsi and could understand what the Imam was saying. To which they replied that, "We are not conversant with Farsi and don't understand the speeches of the Imam at all!" we then asked them why they would come every night to hear his speeches to which they replied: "When we come here and he speaks, we feel a spiritual transformation take place within us."[1]
