According to Chapter 32, why is having a Guru so important, even for someone who is well-read in the scriptures?

Chapter 32 of Sai Satcharitra places immense importance on the role of the Guru. The text explicitly states that even if one has deeply studied the Vedas, Vedangas, Shrutis, and Shastras, all that knowledge is considered "mere chaff" without the Guru's grace. True knowledge is unattainable without it. The chapter further emphasizes that the words spoken from Sai Maharaj's mouth have the power to destroy sins and afflictions, and more importantly, they can cause a devotee to see their own Guru, highlighting that the Guru's grace is the ultimate key to spiritual understanding.
