According to the Satcharitra, what makes a spiritual story or narration truly effective for the listener?

Chapter 21 begins by outlining the ideal impact of a spiritual narration on its audience. It suggests that a speaker's words are only truly successful if the listener is deeply moved. The text states that narrations can be considered futile if they fail to delight the listeners, cause their throats to choke up with emotion, and bring tears of love and joy to their eyes. As mentioned in this chapter, the desired effect is for the listener to sway upon hearing the words and for the hair on their body to stand on end, indicating a profound and visceral connection to the sacred story being told.
