Then there is also a thought connected with this idea: how can one best prepare oneself to utter a certain word effectively? Symbolically speaking, a person may pronounce the same word a hundred times before people, but it is an iron word. A person may say it fifty times, but it is a copper word. A person may say it twenty times, but it is a silver word. And another person may say it only once, and it is a golden word. For instance, a person may talk and talk and talk in order to convince you, he may dispute and discuss and argue and show a thousand examples to make you believe, and the more he wants you to believe, the more he pushes you off. There is another person who tells you something perhaps only once, and you cannot help saying: "Yes, I believe it, I understand it, I am convinced."
