Which chapter transitions from a philosophical discussion on non-duality to a story about a skeptical visitor to illustrate the point?

Chapter 35 is structured in this exact way. It opens with a lyrical description of how experiencing Sai dissolves the 'triad' of perception (e.g., the seer, seen, and seeing) into a single, non-dual reality. After establishing this high spiritual state, the text explicitly notes that the book has 'drifted' and pivots to ground the concept in a practical narrative. As Chapter 35 continues, it introduces the story of Kaka Mahajani’s friend, a man 'averse to idol worship' who came with 'clinical curiosity,' serving as a concrete example of how Sai could shatter a person's preconceived notions.
