Using the metaphors in Chapter 52, describe the state of non-duality achieved by a devotee.

Chapter 52 uses vivid imagery to explain the state of non-duality. It compares a devotee taking refuge in the Guru to a river embracing the ocean, at which point the river forgets its own 'river-ness' and merges completely. In this state, the Guru does not leave any sense of duality in the devotee. Another powerful metaphor used is that of two lamps embracing, which immediately become one light. This illustrates how the state of duality vanishes instantly upon union, resulting in a singular, unified consciousness, leading the devotee mysteriously toward the supreme goal of liberation.
