How did Sai Baba characterize the author's role in the creation of his biography, and what did He promise in return for surrender?

Sai Baba characterized the author's role as being "merely a pretext" in the writing of the book. As mentioned in Chapter 2, He made it clear that He Himself would be the true author, stating, "I myself shall write my own story!" and "I myself shall enter with 'I-ness' and write with my own hand." The key condition for this divine collaboration was the author's complete surrender and dissolution of the ego. In return for this surrender, Sai Baba promised not just his "full help" with the book, but also that He would "serve in all ways in his home," signifying a total and all-encompassing divine support in the devotee's life.
