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

Chapter 52 employs several vivid analogies to illustrate the principle of non-duality. It compares a devotee taking refuge at Sai's feet to a river entering the ocean and becoming the ocean itself. Another analogy is of salt entering the ocean and instantly becoming one with it. The text also mentions how two lamps, when they embrace, become a single light, causing the state of duality to vanish. These comparisons from Chapter 52 emphasize that when devotees relinquish their 'I-ness' and merge with Sai, no sense of separation remains, and they become equal with Him.
