How does the author describe the ideal effect of Baba's stories on a listener at the start of Chapter 21?

At the beginning of Chapter 21, the author reflects on the profound impact that narrations about Sai Baba should have. He posits that a speaker's words are in vain if the listener is not deeply moved, to the point where the hair on their body stands on end. He considers narrations futile if they do not delight the listeners, cause their throats to choke up with emotion, and bring tears of love and joy to their eyes. This sets a high standard for spiritual storytelling, indicating that its purpose is not mere information, but a deep, emotional, and transformative experience, which he attributes to Baba's captivating speech and extraordinary methods.
