Can you explain the analogy of the salt doll mentioned in Chapter 18 and what it signifies about a devotee's relationship with the Sadguru?

Chapter 18 uses a powerful analogy to describe the experience of a devotee approaching the Sadguru. It asks, "If a doll made of salt enters the ocean to take a bath, can it ever return?" The text answers that this can never happen, suggesting a complete dissolution or merging. This metaphor illustrates the state of a devotee who truly approaches the Guru. Just as the salt doll merges with the ocean, losing its individual form to become one with the whole, the devotee merges with the Guru's infinite nature, losing the false sense of individual self. As described in Chapter 18, this signifies a complete surrender and ultimate union from which one does not return to their former limited state.
