What are some of the metaphors used in Chapter 52 to describe the merging of a devotee with Sai and the concept of non-duality?

Chapter 52 employs several powerful analogies to illustrate the principle of non-duality between a devotee and the Guru. It explains that when a devotee takes refuge at Sai's feet, duality vanishes. This is compared to a river entering the ocean, which then forgets its own 'river-ness' and becomes the ocean itself. Another metaphor is that of salt entering the ocean and becoming one with it instantly. The chapter also uses the image of two lamps embracing, after which the state of duality disappears, leaving only one unified light. These examples from Chapter 52 beautifully convey how a devotee, by relinquishing their 'I-ness' or ego, becomes equal and one with Sai.
