What powerful analogies does Chapter 52 use to describe the state of non-duality achieved when a devotee takes refuge in the Guru?

To illustrate the ultimate state of non-duality, Chapter 52 uses two powerful analogies. It explains that when a devotee takes refuge in the Guru, the sense of a separate self dissolves. The first analogy is that of a river embracing the ocean: upon merging, the river forgets its own "river-ness" and becomes one with the vast sea. The second analogy is of two lamps that, when they embrace, become a single source of light, causing the state of duality to vanish immediately. Through these images, the chapter conveys how taking refuge in Sai leads to a state of perfect unity where no sense of duality remains.
