According to Chapter 40, what is the nature of the relationship between a devotee and the Sadguru, and what happens when a devotee seeks exclusive refuge?

The relationship between a devotee and the Sadguru is described with profound depth in Chapter 40. It is likened to a river meeting the ocean; while they have different names, they are essentially one, and upon meeting, all difference vanishes. When a devotee seeks exclusive refuge in the Sadguru with genuine devotion, the Guru grants them His own Guru-nature. Chapter 40 explains that Sai Baba embraces such devotees in His heart, performing shaktipat (transmission of spiritual energy) and destroying the sense of duality. This process dissolves the separate feelings of 'me' and 'you,' making the unattainable attainable.
