Based on Chapter 52, what happens to a devotee who takes complete refuge in the Guru, and what analogy is used to describe this state?

Chapter 52 teaches that when a devotee completely takes refuge in the Guru, the sense of duality and separation is eliminated. The chapter uses a powerful analogy to describe this state of non-duality: 'By embracing the ocean, the river forgets its river-ness.' This illustrates how the individual identity of the devotee merges into the vastness of the Guru. Similarly, Chapter 52 states that when a devotee takes refuge, 'You do not leave any sense of duality in them,' leading them mysteriously toward the supreme goal of liberation while still in the body.
