According to the provided text, what was Sai Baba's role in the creation of his own life story, and what was required of the author?

According to Chapter 2, Sai Baba played the role of the true author of his own life story. He expressed this by telling the writer, "He is merely a pretext; I myself shall write my own story!" To calm the writer's mind, Sai Baba promised his full help and assistance. However, this divine collaboration came with a critical condition: the author was required to completely dissolve his ego and surrender it at Sai's feet. The text states that when the ego is dissolved with no trace remaining, Sai Baba himself would "enter with 'I-ness' and write with my own hand," thus ensuring the work was accomplished by the divine, with the human author serving only as a vehicle.
