How does Chapter 40 describe the relationship between a devotee and the Sadguru, and what analogy is used to illustrate this union?

According to Chapter 40, when a devotee seeks exclusive refuge in the Sadguru with sincere devotion, the Guru grants them His own divine nature. To illustrate this profound union, the chapter uses the analogy of a river and an ocean. While they have different names, they are essentially one in substance, and when they meet, no difference remains between them. In the same way, this chapter explains that Sai Baba embraces those who seek refuge, dissolving the separate feelings of "me" and "you" and making the devotee one with Him.
