According to Chapter 32, why is the grace of a Guru considered more important than scriptural knowledge?

Chapter 32 strongly emphasizes the supreme importance of a Guru's grace for attaining true knowledge. The text posits that even if a person has thoroughly studied the Vedas, Vedangas, and other Shastras, all that learning is considered "mere chaff" without the grace of a Guru. It is the Guru's blessing that transforms scriptural information into realized knowledge. As stated in Chapter 32, the words from Sai's mouth are so powerful that they can cause a seeker to see their own Guru, signifying that the Guru's grace is the essential catalyst for spiritual realization, far beyond academic study alone.
