Chapter 6 mentions the concept of non-duality (Advaita). How does the text explain the Sadguru's role in helping a devotee realize this state?

Chapter 6 explains that the Sadguru plays a pivotal role in a devotee's realization of non-duality, or Advaita. The text states that by looking at Sai Baba's beautiful form, the devotee experiences supreme bliss. The Sadguru awakens the sense of 'I am He' (Soham) within the devotee, revealing their innate bliss. As mentioned in Chapter 6, this process dissolves the sense of 'me and mine,' which is the root of dualistic thinking. By dissolving this ego-centric perspective, the Sadguru manifests the harmony of non-duality right there for the devotee to experience.
