How does the beginning of Chapter 21 describe the ideal characteristics of a spiritual narration and its audience?

The opening verses of Chapter 21 set a standard for an effective spiritual discourse. It posits that a speaker's words are rendered useless if the listener is not moved to the point where their "hair on the body does not stand on end." The narration is considered futile if it fails to delight the listeners, cause their throats to choke with emotion, or bring tears of love and joy to their eyes. This section of the chapter emphasizes that a truly impactful spiritual story requires a deep, emotional, and visceral response from the audience.
