How does Chapter 52 use analogies to explain the concept of non-duality and the devotee's union with the Guru?

Chapter 52 employs powerful analogies to illustrate the state of non-duality achieved when a devotee fully surrenders to the Guru. The text explains that just as a river forgets its individual identity as a "river" upon embracing the vast ocean, a devotee who takes refuge in Sai Baba loses any sense of duality or separation from Him. Another beautiful analogy presented in Chapter 52 is that of two lamps. When they embrace, they become one, and the state of duality vanishes, leaving only a single, unified light. These examples convey how Baba led his devotees to liberation by dissolving the illusion of a separate self.
