What is the significance of a Guru and the power of Sai Baba's words as described in Chapter 32?

Chapter 32 profoundly emphasizes the indispensable role of a Guru. It asserts that even if one masters the Vedas, Shrutis, and Shastras, all that knowledge is 'mere chaff' without the Guru's grace, which is essential for attaining true knowledge. The chapter also magnifies the power of Sai Baba's speech, comparing its effect to sacred elements. It states that just as the sight of the Ganga destroys sins, 'the words from Sai's mouth destroy sins and afflictions.' Listening to his words is presented as a sacred act that can lead a devotee to see their own Guru.
