What does Chapter 32 say about the necessity of a Guru for gaining true knowledge?

Chapter 32 strongly emphasizes the indispensability of a Guru for spiritual attainment. It explicitly states that even if one has exhaustively studied the Vedas, Vedangas, Shrutis, and Shastras, true knowledge remains inaccessible without the Guru's grace, dismissing all other efforts as 'mere chaff.' The text asserts that the words from Maharaj Sai's mouth have the power to help a devotee see their own Guru. As Chapter 32 explains, the grace of the Guru is the key that unlocks genuine understanding and helps one navigate the complex and perishable 'tree of worldly existence,' which is born of ignorance.
