How does the author describe the qualities of Sai Baba's teachings and the ideal listener's reaction at the start of Chapter 21?

At the beginning of Chapter 21, the author reflects on the profound impact of spiritual narration and Sai Baba's unique style. He argues that a speaker's words are futile unless the listener is deeply moved—to the point where their hair stands on end, their throat chokes with emotion, and tears of joy flow. Narrations that do not produce this state are considered in vain. The author then specifically praises Sai Baba, stating, "Baba’s speech is captivating, His method of instruction is extraordinary; His actions at every step are innovative." This introduction, found in Chapter 21, sets a standard for spiritual engagement, suggesting it should be a deeply emotional and transformative experience for the devotee.
