How does Sai Baba describe his role versus the devotee's role in the creation of his life story?

As detailed in Chapter 2, Sai Baba clearly defines the roles by stating, "He is merely a pretext; I myself shall write my own story!" This establishes the devotee as a vessel or instrument, while Baba is the true author. He promises his full help and support for the project but requires the devotee to dissolve their ego completely. Once that condition of surrender is met, Sai says, "I myself shall enter with 'I-ness' and write with my own hand." Therefore, the work of hearing, reflecting, or writing is ultimately accomplished by the One to whom it belongs, with the human author serving only as a pretext.
