According to Chapter 18, how does the Sadguru make profound spiritual truths accessible to his followers?

As detailed in Chapter 18, the Sadguru possesses the unique ability to make the incomprehensible comprehensible. The text states that the Guru can effortlessly point out with a finger the "Unperceivable One," a truth that even the Vedas and Shrutis debate endlessly. This demonstrates the Guru's power to provide direct, experiential knowledge that transcends intellectual debate. Furthermore, the chapter explains that the Guru guides each person according to their individual worthiness, showing them the true path without causing intellectual conflict. Through the Guru's grace, the illusion of duality, such as "mine" and "thine," vanishes, making the ultimate truth accessible.
