Can you explain the concept of dissolving duality as it is presented in Chapter 40 of the Shri Sai Satcharitra?

Chapter 40 of the Shri Sai Satcharitra explains the dissolution of duality as a key aspect of Sai Baba's grace. It describes how He destroys the "sense of duality" and dissolves the separate feelings of "me" and "you" for those who seek exclusive refuge in Him. The text uses the powerful analogy of a river and an ocean, which have different names but are essentially one; when they meet, no difference remains. Similarly, as the chapter explains, when a devotee surrenders with true devotion, the Sadguru grants them His own divine nature, eliminating the separation between the worshipper and the worshipped.
