What was Sai Baba's direct role and conditions for the creation of his biography?

According to Chapter 2, Sai Baba's role was not just supportive but primary. He gave his full permission and help, stating, "He is merely a pretext; I myself shall write my own story!" This reveals that Baba saw himself as the true author, using the writer as a vessel. The main condition He set was the complete dissolution of the writer's ego and its surrender at His feet. For one who acts this way, Baba promised not only to assist with the book but to serve them in all ways. This process required the author to let go of his 'I-ness' so that Sai could enter and write with His own hand.
