According to Chapter 18, what are some of the ways the Sadguru is described using metaphors?

Chapter 18 uses several powerful metaphors to describe the Sadguru. It hails the Guru as the "Ruler of Maya," who helps devotees see the world as an illusion. The text compares the Guru to the monsoon rain clouds, which lovingly shower the water of self-bliss upon everyone. Furthermore, as described in Chapter 18, it presents a profound analogy of a salt doll entering the ocean; just as the doll dissolves and becomes one with the water, a seeker who approaches the Guru merges with the divine and cannot return to their former state of separateness. This illustrates the transformative and unifying power of the Guru's grace.
