What analogies does Chapter 52 use to describe the union of a devotee with Sai and the disappearance of duality?

Chapter 52 uses several powerful analogies to illustrate the merging of a devotee with the Guru. It states that when a devotee takes refuge at Sai's feet, any sense of duality vanishes. The chapter compares this to a river entering the ocean and forgetting its 'river-ness' to become the ocean itself. Other analogies mentioned include two lamps embracing to become one light, salt instantly becoming one with the ocean it enters, and the inseparability of scent from camphor or light from the sun. Through these examples, Chapter 52 conveys that by relinquishing their 'I-ness,' devotees become equal with Sai, eliminating all duality.
