Chapter 40 uses the analogy of a river and an ocean. Can you explain the spiritual significance of this metaphor in the context of the Guru-devotee relationship as described in the chapter?

Chapter 40 of the Shri Sai Satcharitra employs the powerful metaphor of a river meeting the ocean to explain the profound union between a devotee and the Sadguru. The text states that while a river and ocean have different names, in essence, they are one, and when they meet, no difference remains. Spiritually, this signifies the dissolution of the devotee's individual ego and the sense of duality or separateness ('me' and 'you'). As detailed in this chapter, when a devotee seeks exclusive refuge in the Sadguru with true devotion, the Guru embraces them and grants them His own divine nature. This merging is the ultimate goal, where the devotee's consciousness, like the river, merges completely into the vast, boundless consciousness of the Guru, who is like the ocean.
