What instructions did Sai Baba give for writing his life story, and what was the main condition he set?

Sai Baba gave his full permission and support for the creation of a collection of his stories and experiences. As detailed in Chapter 2, He revealed that the author was merely a pretext and that He Himself would write His own story to fulfill the devotee's wish. The primary condition He set was that the author must completely dissolve his ego and surrender it at Sai's feet. Baba promised that for one who acts this way, He would provide full assistance not just for the book, but in all aspects of their life, as He Himself would enter with 'I-ness' and write with His own hand once the ego was gone.
