Using the analogies from the text, how does Chapter 52 explain the concept of non-duality between a devotee and Sai Baba?

Chapter 52 uses several powerful analogies to explain the state of non-duality achieved by a devotee who takes refuge at Sai's feet. It compares this union to a river entering the ocean and becoming the ocean itself, or salt entering the ocean and instantly becoming one with it. Another analogy is of two lamps embracing to become one, where the duality vanishes, leaving only a single, unified light. The chapter also asks rhetorical questions to illustrate this inseparability, such as whether the scent can remain separate from camphor or light from the sun. In this state, the devotee relinquishes their "I-ness" and becomes equal with Him, leaving no sense of duality.
