Based on Chapter 32, what is the significance of a Guru's grace in attaining knowledge?

Chapter 32 places supreme importance on the grace of a Guru for attaining true knowledge. The text makes a powerful statement that even if a person has thoroughly studied the Vedas, Vedangas, and other scriptures like the Shrutis and Shastras, all that effort is considered "mere chaff" without the Guru's grace. It posits that genuine knowledge is impossible to achieve otherwise. Furthermore, the chapter suggests that the words from Sai Baba's mouth are so potent that they can destroy sins and afflictions, and listening to them can even lead a devotee to see their own Guru, highlighting the transformative power of a Sadguru.
