How does Chapter 18 contrast the Guru's guidance with the debates of the Vedas and Shrutis?

Chapter 18 draws a clear distinction between complex scriptural debates and the Guru's direct guidance. The text notes that the Vedas and Shrutis debate day and night about the "Unperceivable One," indicating a path of intellectual and abstract inquiry. In contrast, the Guru is shown to point out this very same Unperceivable One "with a finger, effortlessly, to Your devotees." This highlights the Guru's unique ability to make the highest spiritual truths, which are otherwise the subject of endless philosophical discussion, directly and easily accessible to a sincere seeker through grace and simple instruction, as described in this chapter.
