How does Chapter 18 contrast the Sadguru's teaching method with scriptural debates?

According to Chapter 18, the Sadguru offers a direct and effortless path to divine understanding that transcends complex intellectual debates. The text notes that while the Vedas and Shrutis may debate endlessly about the nature of the "Unperceivable One," the Sadguru can simply point it out "with a finger, effortlessly" to their devotees. This highlights the Guru's role in providing experiential knowledge over theoretical arguments. As Chapter 18 suggests, this grace eliminates the false logic of "mine" and "thine," providing a clear, intuitive path to truth for each person according to their readiness.
