How does Chapter 21 describe the ideal effect of spiritual narration on a listener?

Chapter 21 begins by outlining the profound and emotional impact that true spiritual stories should have on an audience. It suggests that a speaker's words are wasted if the listener does not emotionally react. According to the text, narrations are considered futile if "the listeners are not delighted, the throat does not choke up with emotion, and tears of love and joy do not flow from the eyes." The chapter further notes that if the listener doesn't sway upon hearing the words or if the hair on their body doesn't stand on end, the storytelling has gone in vain, emphasizing that these accounts are meant to be deeply moving and transformative.
