How does Chapter 40 explain Sai Baba's power to remove the sense of duality in his followers?

As detailed in Chapter 40, Shri Sai Samarth possesses the divine ability to destroy the sense of duality, dissolving the separate feelings of "me" and "you." When a devotee seeks exclusive refuge and offers a full prostration, Sai embraces them. The chapter uses the analogy of a river merging with the ocean; though they have different names, they become one in essence. Similarly, when a devotee shows true devotion, the Sadguru grants them His own Guru-nature, making the unattainable attainable and erasing the distinction between the individual and the Guru.
