What analogies does Chapter 52 use to illustrate the concept of a devotee merging with the divine and overcoming duality?

In Chapter 52, powerful analogies are used to describe the state of non-duality. It explains that when a devotee takes refuge, any sense of duality is removed. This is compared to a river embracing the ocean and completely forgetting its own 'river-ness' as it becomes one with the larger body of water. Another metaphor presented is that of two lamps which, upon embracing, become one; the state of duality vanishes instantly, leaving only a single, unified light. These images illustrate the complete merging of the devotee with the divine.
