How did Sai Baba instruct the author to approach writing his life story?

According to Chapter 2, Sai Baba provided very specific guidance for the creation of his biography. He encouraged the author to keep a record of stories and experiences, promising his full help. Baba's profound instruction was that the author was merely a pretext, and that He Himself would write His own story. The essential condition for this divine assistance was that the devotee must completely dissolve his ego and surrender it at Baba's feet. For one who acts this way, Baba promised not only help with the book but to serve them in all ways in their home.
