Can you explain how Chapter 6 describes Sai Baba helping a devotee achieve the state of non-duality (Advaita)?

Chapter 6 delves into the advanced spiritual process of realizing non-duality. It explains that by gazing upon Sai Baba's beautiful form, a devotee experiences supreme bliss. More significantly, the Sadguru actively awakens the inner sense of 'I am He' (Soham) in the devotee, which reveals their innate bliss. As this happens, Sai dissolves the devotee's sense of 'me and mine,' which is the core of ego-consciousness. This dissolution of the ego, which the chapter describes as being burnt to ashes by the Guru's touch, leads to the manifestation of the harmony of non-duality, or Advaita, where the separation between the individual and the divine vanishes.
