How did Sai Baba sanction the creation of his biography, and what role did the author play in it?

According to the narrative in Chapter 2, Sai Baba felt compassion for the author and granted permission to create a collection of his stories and experiences. Baba assured the author, "My full help is with it." However, he made it clear that the author was merely a pretext. Sai Baba declared, "I myself shall write my own story!" The condition for this divine assistance was that the author must completely dissolve his ego and surrender it at Baba's feet. For a devotee who acts this way, Baba promised not only to assist with the story but to serve them in all ways. The work of writing was thus accomplished by the One to whom it belonged, with the human author serving only as an instrument.
