What was Sai Baba's promise and condition for helping the author write his stories?

In Chapter 2, Sai Baba provides His full support for the project but with a crucial condition related to the author's ego. He stated, "He is merely a pretext; I myself shall write my own story!" The condition was that the author must dissolve his ego and surrender it completely at Sai's feet. To a devotee who acts in this way, Sai Baba promised not only full assistance with the book but also to serve them in all ways in their home. The core message was that once the ego vanishes, Sai Himself would enter with 'I-ness' and write the stories, making the human author a mere instrument for the divine work.
