According to Chapter 18, what transformation occurs in a devotee who receives the Guru's grace?

Chapter 18 explains that receiving the Guru's grace leads to a fundamental shift in perception. The text states that if one is fortunate enough to fall within the Guru's grace, the false logic of "mine" and "thine" finds no place. This means the devotee transcends the limited viewpoint of distinguishing between 'our people' and 'strangers,' fostering a sense of unity. Furthermore, this chapter reveals that the Guru can effortlessly point out the Unperceivable One, a concept debated endlessly by scriptures, directly to the devotee, thus guiding them toward ultimate truth.
