Can you explain the concept of non-duality using the analogies presented in Chapter 52?

Chapter 52 powerfully illustrates the concept of non-duality, where a devotee merges with the divine, using several analogies. It compares this union to a river entering the ocean, thereby forgetting its 'river-ness' and becoming the ocean itself. Similarly, a devotee taking refuge at Sai's feet relinquishes their 'I-ness' and becomes one with Him. Other examples cited in Chapter 52 include two lamps embracing to become a single light, salt dissolving instantly into the ocean, and the inseparability of scent from camphor or luster from gold, all emphasizing how duality vanishes upon complete surrender to Sai.
