How does Chapter 52 explain the process of overcoming duality and achieving liberation through devotion to Sai?

Chapter 52 uses powerful metaphors to describe the path to non-duality and liberation. It clarifies that Sai, through the power of love, mysteriously led His faithful devotees toward the supreme goal, liberating them even while they were still in the body. The chapter compares this merging to a river forgetting its own 'river-ness' upon embracing the ocean. In a similar way, when a devotee takes refuge in the Guru, any sense of duality is removed. Another analogy from Chapter 52 is of two lamps becoming one when they embrace, resulting in a single, unified light where the state of duality completely vanishes.
