How does Chapter 18 describe the relationship between a devotee and the Sadguru, and what happens when one approaches the Guru?

Chapter 18 poetically describes the profound and transformative relationship between a devotee and the Sadguru. It uses the powerful metaphor of a salt doll entering the ocean; just as the doll dissolves and becomes one with the water, a devotee who approaches the Sadguru merges with the divine and cannot return to their former state of separation. This analogy, found in Chapter 18, illustrates the complete surrender and dissolution of the individual ego into the boundless grace of the Guru, leading to a state beyond duality.
