According to Chapter 32, what is the relationship between scriptural knowledge and the grace of a Guru?

Chapter 32 places supreme importance on the Guru's grace over mere scriptural learning for attaining spiritual knowledge. The text makes a powerful statement that even if one has exhaustively studied the Vedas, Vedangas, Shrutis, and Shastras, all this accumulated knowledge is considered 'mere chaff' without the grace of a Guru. It posits that true understanding and liberation from the sorrowful 'tree of worldly existence' are unattainable through intellectual pursuit alone. As laid out in Chapter 32, the words from the Guru's mouth, like those of Sai Baba, have the power to destroy sins and afflictions and, most importantly, cause one to see their own Guru, which is the key to genuine spiritual realization.
