Can you explain the concept of non-duality as described in Chapter 52 using the analogies provided?

Chapter 52 elaborates on the concept of non-duality, which is the state where the devotee and the Guru (Sai) become one, losing any sense of separation. The chapter uses several powerful analogies to illustrate this profound spiritual state. It compares the merging of a devotee with Sai to a river entering the ocean and forgetting its "river-ness" to become the ocean itself. Other examples include two lamps embracing to become a single, unified light, salt dissolving instantly into the ocean, the scent being inseparable from camphor, and light from the sun. As stated in this chapter, when a devotee takes refuge at Sai's feet and relinquishes their "I-ness" or ego, no duality remains, and they become equal with Him.
