What was the author's role in writing Sai Baba's story, according to Baba himself?

In Chapter 2, Sai Baba clarifies that the author's role is secondary to his own divine will. While He grants permission and assures the author of his full help, He explicitly states, "He is merely a pretext; I myself shall write my own story!" Baba instructed the author to dissolve his ego and surrender it at His feet. By doing so, Baba promises to give full assistance and says, "Then I myself shall enter with 'I-ness' and write with my own hand." This indicates that the author is a vessel or an instrument, made a pretext for the work that is ultimately accomplished by the One to whom it belongs.
