What metaphors does Chapter 52 employ to illustrate the concept of a devotee merging with the Guru and losing the sense of duality?

To describe the profound union between a devotee and the Guru, Chapter 52 uses two powerful analogies that illustrate the dissolution of individual identity into a greater whole. The first metaphor is that of a river merging with the ocean. Upon embracing the ocean, the river forgets its own 'river-ness' and becomes one with the vast expanse. The second analogy is of two lamps that, when they embrace, become one. In that moment, the state of duality vanishes, and there is only a single, unified light. These examples from the chapter show how, when a devotee takes complete refuge in Sai, the sense of separation or duality is completely removed.
