According to Chapter 32, what is the role of the Guru in attaining knowledge?

Chapter 32 places supreme importance on the Guru's grace for attaining true knowledge. The text explicitly states that even if one has studied the Vedas, Vedangas, and other scriptures, without the Guru's grace, there is no real knowledge, and all such efforts are considered 'mere chaff'. The words from Sai Baba's mouth are presented as being exceptionally powerful, capable of destroying sins and afflictions. Most importantly, as highlighted in Chapter 32, listening to the words from Maharaj Sai's mouth can cause one to see one's own Guru, which is the key to transcending worldly existence.
