Can you explain the metaphors used in Chapter 18 to describe the relationship between a devotee and the Sadguru?

Chapter 18 uses powerful metaphors to illustrate this relationship. It compares a devotee approaching the Guru to a "doll made of salt" entering the ocean to bathe; just as the doll dissolves and becomes one with the water, so too does the devotee merge with the Guru, losing their individual identity. Later in the chapter, the text likens the Guru to "the rain clouds of the monsoon, showering the water of self-bliss with love," signifying that the Guru generously and lovingly bestows bliss upon all without distinction.
