How does Chapter 32 explain the importance of a Guru's grace compared to scholarly learning?

Chapter 32 makes a very strong case for the necessity of a Guru's grace over mere intellectual or scriptural knowledge. The text states that even if one has thoroughly studied the Vedas and Vedangas or recited Shrutis and Shastras, there can be no true knowledge without the grace of a Guru. In fact, the chapter dismisses all such scholarly pursuits as "mere chaff" in the absence of this divine grace. This establishes a core spiritual principle that realization is not achieved through study alone but is a gift bestowed by a true Master.
