How did Sai Baba authorize the writing of his life story, and what was the main condition He set?

According to Chapter 2, Sai Baba gave his full authorization and blessing for his stories to be collected. He stated, "My full help is with it. He is merely a pretext; I myself shall write my own story!" This indicates that Baba intended to guide the process directly. The main condition He set for the author was the complete dissolution of the ego. Baba instructed, "He should dissolve his ego and surrender it at my feet. To one who acts thus in life, I give full assistance." In return for this surrender, Baba promised not only to help with the book but to serve the devotee in all ways in his home.
