Based on Chapter 40, what is Sai Baba's approach to duality and the relationship between a devotee and the Guru?

Chapter 40 explains that Sai Baba's grace actively destroys the sense of duality, unifying the devotee with the Guru. The text describes how Sai, by placing His hand upon a devotee's head, performs shaktipat (transmission of spiritual energy) and dissolves the separate feelings of "me" and "you." The chapter uses a powerful analogy, comparing the devotee and Guru to a river and an ocean; though they have different names, they become one when they meet. As Chapter 40 illustrates, when a devotee seeks exclusive refuge, Sai grants them His own Guru-nature, embracing them fully and making the unattainable attainable through this spiritual union.
