According to the beginning of Chapter 18, what is the effect of receiving the Sadguru's grace?

As detailed in Chapter 18, receiving the Sadguru's grace has a profound and transformative effect on a devotee. The text explicitly states that when one is fortunate enough to fall within the Guru's grace, the false logic of 'mine' and 'thine' completely vanishes. This means the ego-driven distinctions between 'ours' and 'strangers' find no place, leading to a state beyond duality. The chapter uses the analogy of a salt doll entering the ocean to illustrate how a devotee merges with the Guru, suggesting a complete dissolution of the individual self into the supreme consciousness.
