Can you explain the experience of non-duality (Advaita) that a devotee can attain through the Sadguru, based on Chapter 6?

Chapter 6 of the Sai Satcharitra delves into the profound spiritual state of non-duality, or Advaita, that a Sadguru can bestow. It describes how the Guru's presence awakens the intrinsic sense of 'I am He' (Soham) within the devotee, revealing a state of innate bliss. This realization directly leads to the dissolution of the sense of 'me and mine'—the very foundation of ego and separateness. By dissolving this duality, the Sadguru manifests the harmony of non-duality, where the devotee experiences a unified consciousness with the divine.
