What metaphors does Chapter 18 use to explain the relationship between a Guru and a devotee?

Chapter 18 employs several powerful metaphors to illustrate the Guru-devotee relationship. The most prominent one compares a devotee approaching the Guru to a salt doll entering the ocean. As the chapter explains, just as the doll dissolves and becomes one with the water, a devotee merges with the Guru and cannot return to their former state of separation. Another beautiful metaphor presented in Chapter 18 is that of the Guru being like 'the rain clouds of the monsoon.' These clouds shower the 'water of self-bliss with love' upon all, indicating the Guru's impartial and abundant grace.
