According to Chapter 32, what is the importance of a Guru in one's spiritual journey?

Chapter 32 places the utmost importance on the role of the Guru for attaining true knowledge. The text makes a powerful statement that even if a person has extensively studied the Vedas, Vedangas, and other scriptures, this knowledge is considered 'mere chaff' without the Guru's grace. It suggests that spiritual realization is impossible without a Guru's guidance. The chapter further highlights that listening to the words from the Sadguru's mouth, like those of Sai Baba, has the power to destroy sins and afflictions and, most profoundly, can lead a devotee to see their own Guru. This theme is central, as Chapter 32 prepares the reader for a story that Baba himself will narrate about his own 'unexpected Guru-darshan'.
