What key analogies does the author use in Chapter 18 to explain the relationship between a devotee and the Guru?

Chapter 18 employs several powerful analogies to illustrate the profound relationship between a devotee and the Guru. One of the most striking comparisons is that of a salt doll entering the ocean to bathe; just as the doll dissolves and cannot return, a devotee who approaches the Guru merges completely and loses their separate identity. Another beautiful analogy presented in the chapter is the Guru as monsoon rain clouds. This image effectively conveys the idea that the Guru lovingly and indiscriminately showers the 'water of self-bliss' upon all, highlighting the universal and generous nature of the Guru's grace.
