What analogy does Chapter 40 use to explain the spiritual union between a devotee and the Sadguru?

In Chapter 40, the text uses a powerful analogy to explain the union between a devotee and the Sadguru. It compares the devotee to a river and the Guru to an ocean. While they have different names and appear separate, they are in essence one. When the river meets the ocean, particularly during the rainy season, no difference remains between them as they merge completely. Similarly, the chapter explains, when a devotee seeks exclusive refuge in the Sadguru with true devotion, the Guru grants them His own nature, and the feeling of separation between "me" and "you" is dissolved.
