According to the beginning of Chapter 21, what makes a narration or story truly effective and meaningful?

The introduction to Chapter 21 sets a high standard for both storytelling and listening. It posits that a speaker's words are futile if the listener is not deeply moved. The signs of an effective narration, as described in this chapter, are physical and emotional: the listener should sway upon hearing the tale, the hair on their body should stand on end, their throat should choke up with emotion, and tears of love and joy should flow from their eyes. The text suggests that narrations are pointless unless the listeners are delighted in this profound way, highlighting the captivating power of Baba's speech and teachings.
