How does Chapter 32 emphasize the necessity of a Guru's grace for spiritual progress?

Chapter 32 places immense importance on the role of a Guru for achieving true knowledge. The text explicitly states that even if a person has studied the Vedas, Vedangas, and other scriptures extensively, all that learning is 'mere chaff' without the Guru's grace. The chapter builds anticipation for a story that Baba himself will narrate about his own 'unexpected Guru-darshan,' framing it as a wondrous and pivotal event. Furthermore, Chapter 32 suggests that the words from Maharaj Sai's mouth are so potent that they can cause a listener to see their own Guru, reinforcing the central idea that Guru's grace is the indispensable element for spiritual realization.
