According to Chapter 32, what is the importance of a Guru's grace in the pursuit of knowledge?

Chapter 32 places supreme importance on the necessity of a Guru's grace for attaining true knowledge. The text makes a powerful statement that even if a person has thoroughly studied the Vedas and other scriptures, all that learning is 'mere chaff' without the Guru's blessing. It posits that genuine knowledge is unattainable without this grace. As mentioned in Chapter 32, the words spoken from Sai Baba's mouth are considered potent enough to destroy sins and afflictions, and listening to them allows a devotee to truly 'see one's own Guru.' This emphasizes that direct guidance from a Sadguru is superior to mere scriptural scholarship.
