Can you explain how Chapter 6 connects Sai Baba's grace with achieving non-duality (Advaita) and overcoming the ego?

Chapter 6 of the Sai Satcharitra explains that Sai Baba's grace is the key to dissolving the ego and realizing non-duality (Advaita). The text describes the 'wondrous' touch of the Guru's hand, stating it can burn the 'subtle body (ego)' into ashes, something not even the fire of cosmic dissolution can do. According to the teachings in Chapter 6, Sai Baba's grace actively works to awaken the inherent spiritual truth of 'I am He' (Soham) within the devotee. This awakening of innate bliss leads to the dissolution of the sense of 'me and mine,' which is the very foundation of the ego. By removing this illusion of separation, He manifests the harmony of non-duality.
