How does Chapter 32 explain the importance of having a Guru for gaining knowledge?

Chapter 32 strongly emphasizes that a Guru's grace is essential for attaining true knowledge. The text explicitly states that even if one has thoroughly studied the Vedas, Vedangas, and other Shastras, all that effort is considered mere "chaff" without the grace of a Guru. As mentioned in the chapter, the words from Sai Baba's mouth are so potent they can destroy sins and afflictions, similar to the purifying sight of the Ganga river. Ultimately, Chapter 32 suggests that listening to the Guru's words is what allows a disciple to truly see their own Guru and access genuine spiritual understanding, which scholarly learning alone cannot provide.
