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

To illustrate the profound state of non-duality, Chapter 52 uses two vivid analogies to describe the merging of a devotee with the Guru. The first is that of a river and the ocean: "By embracing the ocean, the river forgets its river-ness." This signifies the devotee losing their individual, separate identity upon taking complete refuge. The second analogy mentioned in the chapter is of two lamps becoming one: "Two lamps become one when they embrace; immediately the state of duality vanishes, and there is only one light in unity." Both metaphors effectively convey the complete dissolution of the sense of 'two-ness' and the experience of ultimate oneness with the divine.
