How does the beginning of Chapter 21 describe the powerful impact that a Guru's stories should have on the listeners?

The introduction to Chapter 21 vividly describes the ideal, transformative effect of a Guru's narration on an audience. It suggests that the speaker's words are considered futile or in vain if the listener does not experience a profound physical and emotional reaction. According to the text, a successful narration is one in which "the listener does not sway upon hearing them, if the hair on the body does not stand on end." Furthermore, the stories are deemed 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 from the eyes." This passage from Chapter 21 emphasizes the captivating, innovative, and heart-opening power inherent in Baba's speech and method of instruction.
