How does Chapter 40 explain the concept of a devotee merging with the Sadguru?

Chapter 40 uses a powerful analogy to illustrate the merging of a devotee with the Guru. It compares the relationship to that of a river and an ocean, which have different names but are essentially one. When they meet, no difference remains. Similarly, the chapter explains that when a person seeks 'exclusive refuge in the Sadguru with devotion,' the Guru grants them His own divine nature. This spiritual union is further described as Sai embracing those who prostrate fully, dissolving the separate feelings of 'me' and 'you' and taking them into his heart.
