How does Chapter 6 explain the Sadguru's role in helping a devotee realize non-duality (Advaita) and the 'Soham' state?

Chapter 6 of the Sai Satcharitra explains that the Sadguru is instrumental in guiding a devotee towards the advanced spiritual state of non-duality. The text explicitly mentions that the Guru awakens the sense of 'I am He' (Soham), which is the realization of one's identity with the divine. By revealing this innate bliss, the Sadguru simultaneously dissolves the devotee's sense of 'me and mine,' which is the root of dualistic perception. As Chapter 6 states, this process manifests the harmony of non-duality (Advaita), where the distinction between the self and the ultimate reality collapses.
