Can you explain how Chapter 6 says Sai Baba helps a devotee experience non-duality (Advaita)?

Chapter 6 explains that Sai Baba guides his devotees toward the experience of non-duality, or Advaita, through his divine presence and grace. The text states that by looking at His beautiful form, a devotee's throat can choke with supreme bliss and manifest the eight-fold emotions. More specifically, as mentioned in this chapter, the Sadguru awakens the sense of 'I am He' (Soham) within the devotee, revealing their innate bliss. This process directly dissolves the sense of 'me and mine,' which is the root of dualistic thinking, and manifests the harmony of non-duality right then and there.
