Chapter 6 mentions Advaita and the ego. How does it explain the Sadguru's role in helping a devotee achieve non-duality and destroy their ego?

Chapter 6 provides deep insights into the Sadguru's power to guide a devotee towards non-duality (Advaita). The text explains that the wondrous touch of the Guru’s hand can burn the subtle body of ego into ashes. Furthermore, by awakening the sense of 'I am He' (Soham) and revealing innate bliss, the Sadguru dissolves the sense of 'me and mine,' thereby manifesting the harmony of non-duality. The chapter emphasizes that when ego peeps out during a task like writing, Sai suppresses it, ensuring the disciple's focus remains pure.
