How does Chapter 18 describe the Sadguru's ability to reveal spiritual truths compared to traditional scriptures?

Chapter 18 explains that the Sadguru possesses a unique ability to make the divine comprehensible to devotees. While scriptures like the Vedas and Shrutis may debate day and night about the nature of the 'Unperceivable One,' this chapter states that the Guru can point to this ultimate reality 'with a finger, effortlessly.' This highlights the Guru's role as a direct and accessible guide to spiritual truths that might otherwise remain abstract. Through the Guru's grace, the false logic of 'mine' and 'thine' also dissolves, leading to a unified perspective not always achieved through scriptural debate alone.
