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

Chapter 32 makes a powerful case for the indispensable role of a Guru. It asserts that even if a person has thoroughly studied the Vedas, Vedangas, and other scriptures, all that learning is considered "mere chaff" without the grace of a Guru. True knowledge, it argues, is unattainable through scholarly pursuit alone. The chapter reinforces this by stating that the very words from Maharaj Sai's mouth have the power to make one see one's own Guru, positioning the Guru's grace as the essential, non-negotiable element for spiritual realization, far surpassing intellectual accomplishment.
