According to the text, what happens to a person's mindset when they receive the Guru's grace?

Chapter 18 explains that receiving the Guru's grace brings about a fundamental transformation in a person's perception and mindset. The text states that 'If, by a stroke of fortune, one falls within Your grace, then the false logic of "mine" and "thine" (this one is ours, that one is a stranger) finds no place.' This means that the grace of the Sadguru dissolves the illusion of duality and separateness. A person who receives this grace transcends the limited ego-centric view of the world. Instead, they begin to see the underlying unity in all of creation. As Chapter 18 further elaborates, the Guru is the one who shows the true path and teaches the knowledge of the Self, guiding the devotee away from such false logic and towards a state of non-duality.
