Can you explain the concept of non-duality between a devotee and Sai Baba using the analogies provided in Chapter 52?

Chapter 52 powerfully illustrates the concept of non-duality, where the devotee merges completely with the Guru. It states that upon taking refuge at Sai's feet, any sense of duality vanishes. The chapter uses several vivid analogies to explain this state. For instance, it compares the devotee to a river that enters the ocean and forgets its "river-ness," becoming the ocean itself. Another analogy is of salt dissolving in the ocean, becoming one with it instantly. Chapter 52 also mentions how two lamps, when they embrace, become a single light, and how scent cannot be separated from camphor. In this way, devotees relinquish their "I-ness" and become one with Sai.
