A speaker’s tone of voice is a key factor that will make a major difference whether he will have a positive effect or not. Matters pertaining to cold logic do not need a special tone of voice. However, when your goal is to arouse elevated spiritual feelings in someone, it is important to speak in a tone of voice that will inspire the appropriate elevated state.

Today, when speaking to someone about a personal matter, be conscious of how your tone of voice can enhance your message.
