How does Chapter 18 contrast the path of intellectual debate with the experience of the Sadguru's grace?

Chapter 18 highlights the limitations of intellectualism compared to the direct experience provided by a Guru. It notes that the Vedas and Shrutis engage in endless debate about the "Unperceivable One," implying a complex and perhaps unresolvable intellectual pursuit. In contrast, the chapter states that the Sadguru can point out this same divine reality "with a finger, effortlessly, to Your devotees." This grace-filled path is shown to be superior, as it operates "without creating even a bit of intellectual conflict." By receiving the Guru's grace, a devotee transcends the false logic of "mine" and "thine," achieving a state of unity that intellectual debate alone cannot provide.
