What analogies are used in Chapter 52 to describe the state of non-duality achieved by a devotee who takes refuge in Sai Baba?

Chapter 52 uses several beautiful analogies to illustrate the complete merging of a devotee with the Guru, where all sense of duality vanishes. It compares this union to a river entering the ocean, which forgets its own 'river-ness' and becomes the ocean itself. Another powerful image used is that of two lamps embracing, where the duality of two separate flames disappears and there is only one unified light. The chapter further explains this oneness by asking rhetorically if scent can remain separate from camphor, light from the sun, or luster from gold. Finally, it mentions that just as salt entering the ocean instantly becomes one with it, devotees who relinquish their 'I-ness' at Sai's feet become equal with Him.
