How does Chapter 18 describe the experience of a devotee who approaches the Sadguru?

Chapter 18 uses a powerful metaphor to describe the experience of a devotee approaching the Sadguru. It compares the devotee to a salt doll entering the ocean for a bath, questioning if it could ever return. The text states this can never happen, implying that one who truly approaches the Guru dissolves their individual identity and merges with the divine, much like the salt doll dissolves into the vastness of the ocean. This analogy, found in the opening verses of Chapter 18, illustrates the complete surrender and transformation that occurs in the presence of the Guru.
