According to the beginning of Chapter 21, what makes a spiritual narration effective, and how does this relate to Baba's stories?

The introduction of Chapter 21 beautifully describes the ideal interaction between a storyteller and a listener in a spiritual context. It suggests that a narration is only successful if it deeply moves the listener, causing them to 'sway upon hearing,' their 'hair on the body' to stand on end, their throat to choke with emotion, and tears of love to flow. The chapter deems narrations futile if they do not elicit such a heartfelt, physical, and emotional response. This is directly related to Sai Baba's stories, as the text describes Baba's speech as 'captivating' and his method of instruction as 'extraordinary.' As stated in Chapter 21, the power of these stories lies in their ability to create a profound and transformative experience for the attentive listener.
