Using the analogies from Chapter 52, can you explain how a devotee achieves unity with the Guru and overcomes duality?

Chapter 52 beautifully illustrates the concept of non-duality through powerful analogies. It explains that Sai Baba leads His faithful devotees towards the supreme goal, liberating them even while they are in their bodies. The chapter compares a devotee taking refuge in the Guru to a river merging with the ocean; just as the river forgets its individual 'river-ness' and becomes one with the ocean, the devotee loses their sense of a separate self. Another analogy used is of two lamps embracing to become one light, at which point the state of duality vanishes instantly, leaving only the unity of a single flame. This describes how the devotee and Guru merge, eliminating any sense of separation.
