How does Chapter 6 describe Sai Baba's method for destroying the ego and revealing the state of non-duality?

Chapter 6 of the Sai Satcharitra delves into the Sadguru's role in spiritual transformation. It states that Sai Baba burns away the subtle body, or ego, into ashes with the mere touch of his hand. He awakens the sense of 'I am He' (Soham) within the devotee, which reveals their innate bliss. By doing so, He dissolves the sense of 'me and mine' and manifests the harmony of non-duality, or Advaita. The chapter also notes that whenever the author's ego would peep out during the writing process, Sai Baba would suppress it with his own hand, demonstrating his active role in diminishing the ego of his disciples.
