Can you explain how Chapter 6 of the Sai Satcharitra connects the Sadguru's grace to the attainment of non-duality (Advaita)?

Chapter 6 provides deep insights into the path to non-duality through the Sadguru's grace. It explains that the Guru's touch has the power to burn away the 'subtle body,' which is the ego. By placing His hand on the devotee's head, the Guru awakens the sense of 'I am He' (Soham), revealing innate bliss. This process, as mentioned in the chapter, dissolves the sense of 'me and mine' right there and then. This dissolution of the individual self and the ego is what manifests the harmony of non-duality, or Advaita, where the distinction between the self and the divine is erased.
