How does Chapter 52 describe the merging of a devotee with the Guru and the concept of non-duality?

Chapter 52 uses powerful metaphors to illustrate the concept of non-duality and the ultimate union between a devotee and Sai Baba. The text explains that when a devotee takes refuge in Sai, He ensures that no sense of duality or separation remains. This is beautifully compared to a river that forgets its individual identity as a 'river' once it merges with the vast ocean. Another analogy provided in Chapter 52 is that of two lamps embracing to become one; in that moment, the state of duality vanishes, leaving only a single, unified light. This demonstrates how Sai leads His devotees to liberation by dissolving the illusion of a separate self.
