What does Chapter 21 say about the qualities of effective spiritual narration and Sai Baba's method of instruction?

The beginning of Chapter 21 reflects on the power of spiritual storytelling. It posits that a speaker's words are in vain if the listener is not moved, if their hair doesn't stand on end, and if their throat doesn't choke with emotion. The text considers narrations futile if they don't delight the listeners and bring tears of love and joy. In this context, Chapter 21 praises Sai Baba, describing His speech as captivating and His method of instruction as extraordinary. Furthermore, it highlights that Baba's actions were innovative at every step, prompting the author to bow his head in reverence at His feet.
