What metaphors are used in Chapter 52 to describe the state of non-duality, or the union of a devotee with the Guru?

Chapter 52 employs powerful metaphors to illustrate the ultimate state of non-duality. It explains that when a devotee takes refuge in Sai, He ensures no sense of duality remains. This union is compared to a river embracing the ocean and, in doing so, forgetting its own 'river-ness' and separate identity. Another beautiful metaphor presented in the chapter is that of two lamps becoming one when they embrace; in that instant, the state of duality vanishes, and there is only a single, unified light. These images convey the complete and total merging of the individual soul with the Supreme.
