Chapter 40 uses the analogy of a river and ocean. What spiritual concept does this analogy illustrate?

The analogy of the river and the ocean in Chapter 40 is used to explain the profound spiritual concept of the dissolution of duality and the devotee's union with the Sadguru. The text notes that while a river and an ocean have different names, they are essentially one in substance. When they meet, no difference remains. Similarly, this chapter teaches that when a devotee seeks exclusive refuge in the Sadguru with true devotion, the Guru grants them His own divine nature, erasing the separation between the individual ("me") and the Guru ("you"). This illustrates the ultimate goal of non-duality, where the devotee merges completely into the Guru's consciousness.
