How does Chapter 18 describe the transformative effect of approaching the Sadguru?

Chapter 18 uses a powerful metaphor to describe the complete merging that occurs when a devotee approaches the Sadguru. It compares this process to a doll made of salt entering the ocean to take a bath, asking rhetorically if it can ever return. The chapter states this can never happen, implying that one who approaches the Guru loses their individual identity and merges with the divine, just as the salt doll dissolves into the ocean. This powerful imagery from Chapter 18 illustrates the ultimate goal of spiritual seeking and the Guru's role in dissolving the ego and the false logic of 'mine' and 'thine'.
