How does Chapter 21 describe the power of spiritual narration and Sai Baba's unique methods?

Chapter 21 opens by emphasizing the profound impact that spiritual stories should have on the listener. It suggests that a speaker's words have been 'in vain' if the listener's 'hair on the body does not stand on end' and if 'tears of love and joy do not flow from the eyes.' Immediately following this, the chapter praises Sai Baba directly, stating, 'Baba’s speech is captivating, His method of instruction is extraordinary; His actions at every step are innovative.' This introduction from Chapter 21 sets a high standard for spiritual discourse and then immediately identifies Sai Baba as a master of this captivating and transformative style of teaching, whose every action was novel and instructive.
