How does the beginning of Chapter 21 describe the ideal way to receive Baba's stories and teachings?

The introduction to Chapter 21 emphasizes the importance of receptive listening and emotional engagement when hearing about Sai Baba. The author suggests that a speaker's words are in vain if the listener does not "sway upon hearing them" or if the "hair on the body does not stand on end." The narration is considered futile if listeners are not delighted, if their throats do not choke up with emotion, and if tears of love and joy do not flow. This chapter highlights that Baba's speech is captivating and His methods are extraordinary, and experiencing these stories should be a deeply moving event.
