How does Chapter 21 describe the ideal reaction of a listener to the stories of a Guru?

The beginning of Chapter 21 sets a high standard for how a listener should engage with a Guru's stories. It suggests that a speaker's words are only truly successful if the listener is deeply moved, swaying upon hearing them and feeling the hair on their body stand on end. The narration is considered futile if it doesn't delight the audience, cause their throats to choke up with emotion, and bring tears of love and joy to their eyes. Chapter 21 emphasizes this profound emotional and physical response as the proper way to receive the captivating and innovative teachings of a master like Sai Baba.
