What transformation occurs in a person's mindset after receiving the Guru's grace, as explained in Chapter 18?

Chapter 18 explains that when a devotee is fortunate enough to fall within the Guru's grace, a fundamental shift in perspective occurs. The text states that under such grace, "the false logic of 'mine' and 'thine' (this one is ours, that one is a stranger) finds no place." This signifies a profound spiritual evolution where the devotee transcends the dualistic thinking that creates separation and conflict. As detailed in this chapter, the Guru's grace effectively dissolves the ego-centric worldview, leading to a more unified and all-encompassing consciousness.
