What is the meaning behind the salt doll analogy presented in Chapter 18?

The analogy of the salt doll in Chapter 18 illustrates the profound and irreversible merging of a devotee with the Guru or the divine. The chapter asks, "If a doll made of salt enters the ocean to take a bath, can it ever return? This can never happen; similar is the case with one who approaches You." This signifies that when a seeker (the salt doll) truly approaches the Sadguru (the ocean), their individual ego and sense of separate self dissolve completely into the vastness of the divine consciousness. The transformation is so total that a return to the previous state of limited identity is impossible.
