Based on the introduction to Chapter 32, what is the connection between Sai's words, the Guru, and overcoming worldly existence?

Chapter 32 establishes a clear connection between listening to the Guru's words and transcending worldly existence. The chapter introduces the metaphor of the "tree of worldly existence," describing it as a perishable, sorrow-filled entity born of ignorance and desire. It then presents the solution: the words from Sai Baba's mouth, who acts as the Guru. The text states that just as sins are destroyed by the sight of the Ganga, the words from Sai's mouth destroy sins and afflictions. It is strongly implied in Chapter 32 that only through the Guru's grace and teachings can one gain the knowledge to see past this illusory tree and find liberation, as even vast scriptural knowledge is useless without it.
