What analogies does Chapter 52 use to explain the concept of non-duality between a devotee and Sai?

Chapter 52 employs several powerful analogies to illustrate the state of non-duality achieved by a devotee. It compares the devotee to a river that, upon embracing the ocean, forgets its 'river-ness' and becomes the ocean itself. Another analogy is of two lamps that, when they embrace, become one light, causing the state of duality to vanish instantly. The text also asks rhetorically if scent can be separate from camphor or luster from gold. Finally, it mentions that just as salt entering the ocean becomes one with it, a devotee taking refuge at Sai's feet relinquishes their 'I-ness,' and no duality remains.
