How does Chapter 52 describe the process of overcoming duality and achieving liberation through devotion to Sai?

Chapter 52 delves into the philosophical concept of overcoming duality by taking complete refuge in the Guru. It teaches that by embracing the Guru, a devotee's sense of separate identity vanishes, much like a river forgets its "river-ness" upon merging with the ocean. The text uses another powerful analogy, stating that when two lamps embrace, they become one light, and the state of duality immediately disappears. This union, facilitated by the power of love, is how Sai Baba led his faithful devotees toward the supreme goal, making them liberated even while still in the body, leaving no sense of duality in them.
