What was Sai Baba's role in the creation of the collection of his stories, and what did he require from the author?

According to Chapter 2, Sai Baba's role was paramount, as he declared, "I myself shall write my own story!" He explained that the author was "merely a pretext." Sai promised his full help on the condition that the author dissolve his ego and surrender it at His feet. For a devotee who acts this way, Sai assured he would not only give full assistance with the story but would also serve them in all ways in their home. He explained that once the ego is gone, He Himself would enter with 'I-ness' and write with his own hand.
