According to Chapter 32, what is the significance of a Guru's grace compared to scriptural knowledge?

Chapter 32 powerfully argues that a Guru's grace is paramount and indispensable for attaining true knowledge. The text explicitly states that even if one has meticulously studied the Vedas, Vedangas, and other Shastras, all that learning is considered mere "chaff" without the Guru's blessing. The chapter posits that the words from Sai's mouth are potent enough to destroy sins and, more importantly, enable a devotee to see their own Guru. Therefore, as explained in Chapter 32, all scholarly pursuits are rendered futile if not accompanied by the essential grace of a Guru, which is the sole pathway to genuine spiritual understanding.
