Chapter 21 begins by describing the ideal response of a listener to spiritual narration. What are these desired effects, and what does the author say about narrations that fail to produce them?

The beginning of Chapter 21 emphasizes the profound connection between the speaker and the listener in spiritual discourse. The author states that the listener should be so moved that they 'sway upon hearing' the words and the 'hair on the body stands on end.' The ideal response also includes the throat choking up with emotion and tears of love and joy flowing from the eyes. According to this chapter, if a narration does not delight the listeners and evoke these deep emotional and physical responses, the speaker's words have 'gone in vain,' and the narrations themselves are considered 'futile.'
