Chapter 52 uses several analogies to describe the union of a devotee with Sai. Could you explain these analogies and what they teach about non-duality?

To illustrate the concept of non-duality, Chapter 52 employs several powerful analogies. It compares the devotee's union with Sai to a river entering the ocean and becoming the ocean itself, or salt instantly becoming one with the ocean upon entering it. Another analogy is of two lamps embracing to become a single, unified light, where the state of duality vanishes. The text also asks rhetorically if scent can be separated from camphor or light from the sun. These examples from Chapter 52 powerfully convey that upon taking refuge at Sai’s feet, all sense of duality and individual "I-ness" dissolves, and the devotee becomes equal with Him.
