How does the narrative of Kaka's friend relate to the chapter's opening description of non-duality and the senses?

Chapter 35 opens by describing a state of non-duality where the devotee's experience of Sai transcends the senses, causing the triad of 'the seer, the seen, and the seeing' to vanish. While the friend of Kaka Mahajani arrived with a strong sense of dualistic separation—himself versus the saint he wouldn't bow to—his experience reflects a shattering of this duality. When he heard Baba's voice, the distinction between the 'hearer' (himself) and the 'heard' (the voice that was both Baba's and his father's) collapsed. This overwhelming sensory and emotional experience, as described in chapter 35, obliterated his preconceived notions and egoic resolve, leading to an act of spontaneous surrender, which is a practical example of the state of non-action and dissolution of self discussed earlier in the chapter.
