According to Chapter 18, what happens to a person who receives the Guru's grace?

According to the teachings presented in Chapter 18, receiving the Guru's grace brings about a profound transformation. The chapter states that when one is fortunate enough to fall within the Guru's grace, the divisive and false logic of 'mine' and 'thine' completely disappears. This means the devotee transcends the ego-driven distinctions between what belongs to them and what belongs to others. Furthermore, the chapter explains that the Guru effortlessly points out the 'Unperceivable One'—Brahman—to his devotees, a truth that even the Vedas and Shrutis debate endlessly. This grace ultimately leads to the dissolution of the individual self, much like a salt doll dissolving in the ocean.
