Why was Sai Baba initially resistant to having his life story written, and what made him finally give his permission?

This question is based on a false premise, as the provided source material does not indicate any initial resistance from Sai Baba. In fact, Chapter 2 shows that upon hearing the proposal, he immediately felt compassion and gave his full support. He is quoted as saying, "A collection of stories, news, and experiences should indeed be made. Keep a record; it is good. My full help is with it." He further explained that the author was merely a pretext and that He himself would write the story, fulfilling the devotee's wish by providing full assistance once the author dissolved his ego.
