How does Chapter 6 describe the Sadguru's role in helping a devotee overcome their ego and achieve spiritual realization?

According to Chapter 6 of the Sai Satcharitra, the Sadguru is the essential guide, or "helmsman," who ensures a devotee's spiritual journey reaches the "far shore." A key aspect of this guidance is the destruction of the ego. The text states that the wondrous touch of the Guru's hand can burn away the subtle body, or ego, into ashes. This divine touch also washes away the accumulated impurities of many past births. As described in Chapter 6, the Sadguru ultimately awakens the sense of 'I am He' (Soham) within the devotee, dissolving the sense of 'me and mine' and manifesting the harmony of non-duality (Advaita), which is the state of ultimate spiritual realization.
