Why does Chapter 32 emphasize the importance of having a Guru so strongly?

Chapter 32 places immense importance on the Guru's role in attaining spiritual knowledge. It states unequivocally that even if a person has studied the Vedas, Vedangas, and other scriptures, true knowledge is unattainable without the Guru's grace; all other learning is dismissed as 'mere chaff.' The chapter builds anticipation for a story told by Baba himself about his own wondrous Guru-darshan. Ultimately, the text suggests that listening to the words from Maharaj Sai's mouth is powerful enough to destroy sins and afflictions and can even lead a devotee to see their own Guru.
