How does Chapter 32 emphasize the importance of having a Guru's grace?

Chapter 32 places supreme importance on the role of a Guru. It explicitly states that even if one has thoroughly studied the Vedas, Vedangas, and other scriptures, all that knowledge is considered "mere chaff" without the Guru's grace. The text asserts that true knowledge is unattainable without this grace. Furthermore, it highlights that listening to the words from Sai Baba's own mouth has the power to make one see their own Guru. As Chapter 32 suggests, just as the sight of the Ganga destroys sins, the words from a Sadguru like Sai destroy both sins and afflictions, guiding a devotee on the spiritual path.
