Chapter 18 uses the metaphor of a salt doll in the ocean. What spiritual concept does this illustrate?

The metaphor of the salt doll, as presented in Chapter 18, illustrates the spiritual concept of the dissolution of the individual self into the divine. The text poses the question of whether a salt doll, after entering the ocean, could ever return, and answers that it cannot. This is then presented as being similar to the case of one who approaches the Sadguru. The metaphor signifies that a true seeker who surrenders to the Guru loses their separate identity and ego, merging completely and becoming one with the Guru's infinite consciousness, much like the salt dissolves and becomes the ocean itself.
