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

Chapter 32 establishes a clear hierarchy between scriptural knowledge and the necessity of a Guru's grace. The text explicitly states that even if one has exhaustively studied the Vedas, Vedangas, and other Shastras, this knowledge is considered 'mere chaff' without the grace of a Guru. It is through the Guru that true knowledge is attained. As Chapter 32 beautifully puts it, the words from Sai's mouth have the power to destroy sins and afflictions and, most importantly, cause one to 'see one's own Guru,' signifying that the Guru's guidance is the ultimate path to spiritual understanding, far surpassing rote learning of scriptures.
