How does Chapter 17 describe the limitations of intellect and the role of the Guru in spiritual realization?

Chapter 17 of the Shri Sai Satcharitra highlights the limitations of human faculties and the indispensable role of a Guru. It states that there is a place where even the sun's rays cannot see, the intellect turns back, and where the steps of the Vedas cannot enter. It is precisely this profound place that the Guru shows with his own hand. This chapter also points out the futility of being 'learned' if one does not know right from wrong and continues to engage in sinful deeds. Similarly, it suggests that knowledge alone does not bring peace to a person whose heart is restless and distracted by greed, reinforcing that a Guru's guidance is essential to navigate the path beyond mere intellectual understanding.
