How does Sai Baba describe the collaborative process of writing his biography, and what is the role of the author's ego?

In Chapter 2, Sai Baba describes a profound and mystical process for the creation of his biography. He explains that the author, Hemadpant, is merely a pretext or an instrument. The core requirement for this divine collaboration is the dissolution of the author's ego. Baba instructs the devotee to 'dissolve his ego and surrender it at my feet.' As Chapter 2 clarifies, when the ego is completely dissolved and no trace of it remains, Baba Himself will 'enter with 'I-ness' and write with my own hand.' This illustrates that the work is not an intellectual exercise by the author but a divine act accomplished by the One to whom it truly belongs.
