Chapter 40 mentions that Sai Baba "destroys the sense of duality." Can you elaborate on what this means based on the text?

Based on the teachings in Chapter 40, destroying the sense of duality refers to dissolving the separate feelings of "me" and "you" between the devotee and the Guru. The text explains that when a devotee offers a full prostration and seeks exclusive refuge, Sai embraces them and removes this feeling of separation. An analogy is provided: just as a river and an ocean have different names but become one when they meet, a devotee who merges with the Sadguru loses their separate identity and is granted the Guru's own nature. This spiritual union, where the distinction between the worshipper and the worshipped disappears, is the essence of overcoming duality as described in this chapter.
