Can you explain the metaphor of the salt doll that is mentioned in Chapter 18?

Chapter 18 uses a powerful metaphor to illustrate the experience of approaching the Sadguru. It asks, "If a doll made of salt enters the ocean to take a bath, can it ever return?" The text confirms that this can never happen. This situation is compared to the state of a devotee who approaches the Sadguru. The metaphor suggests a complete merging or dissolution of the individual self (the salt doll) into the vast, infinite consciousness of the Guru (the ocean). It signifies losing one's separate identity and becoming one with the divine, a process from which there is no return to the former state of individuality.
