How does Chapter 52 explain the merging of the devotee with the Guru and the transcendence of duality?

Chapter 52 uses powerful analogies to describe the process of overcoming duality through devotion. It explains that when a devotee takes refuge in Sai, He ensures that no sense of duality remains, much like a river forgets its own "river-ness" upon embracing the ocean. Another metaphor used in this chapter is that of two lamps becoming one when they embrace, causing the state of duality to vanish and leaving only a single, unified light. This illustrates how Sai Baba, through the power of love, mysteriously led His faithful devotees toward the supreme goal of liberation.
