What was Sai Baba's role in the creation of his life story, and what did he ask of the author?

Sai Baba was the primary force behind the creation of his life story, stating that the author was merely a pretext. According to Chapter 2, Baba felt compassion for the author and granted permission to create a collection of stories. He said, "I myself shall write my own story!" and promised his full help. In return, Baba instructed the author to dissolve his ego and surrender it at his feet. He assured that for one who acts this way, He would not only assist with the story but also serve them in all ways in their home. Baba explained that when the ego is dissolved, He himself enters with 'I-ness' to write the work.
