How does receiving the Guru's grace, as described in Chapter 18, alter a person's perception of others?

Chapter 18 explains that the Guru's grace fundamentally alters one's perception by dissolving the ego-driven sense of separation. The text states that if one is fortunate enough to fall within the Guru's grace, "the false logic of 'mine' and 'thine' (this one is ours, that one is a stranger) finds no place." This means that the grace removes the tendency to create divisions between people. The Guru shows the true path without creating conflict, guiding the devotee away from dualistic thinking and towards a more unified, non-judgmental worldview where the concept of 'otherness' disappears.
