"Of the powerful arms of destruction that man has been able to invent, the most terrible- and most cowardly- is the word. Fists and firearms at least leave some blood remaining. Bombs destroy houses and streets. Poisons can be detected. The master says: “The word can destroy without leaving a clue. Children are conditioned for years by their parents, men are impiously criticized, women are systematically massacred by the words of their husband. The faithful are kept away from religion by those who regard themselves as the interpreters of the voice of God. Verify whether you are making use of this weapon. See whether others are using this weapon on you. And prevent either of those from continuing.”
- Paulo Coelho, "Maktub"
