Can you explain the concept of non-duality and merging with Sai as described with analogies in Chapter 52?

Chapter 52 uses several powerful analogies to explain the principle of non-duality, where the devotee merges with the divine. It teaches that when a devotee takes refuge at Sai's feet, the sense of a separate self or duality vanishes. This is compared to a river entering the ocean and forgetting its "river-ness," or salt instantly becoming one with the ocean upon contact. As stated in this chapter, just as two lamps embracing become one unified light, devotees who relinquish their "I-ness" become one with Him. The text reinforces this by asking if scent can be separate from camphor, illustrating the complete and inseparable union that devotion brings.
