According to the source text, what were Sai Baba's specific instructions and promises regarding the writing of his life story?

Sai Baba directly addressed the creation of his biography, as detailed in Chapter 2. He gave his full permission and support, stating, "A collection of stories, news, and experiences should indeed be made. My full help is with it." More profoundly, He revealed that the author was merely a pretext and that He Himself would write His own story. The primary condition was for the author to completely dissolve his ego and surrender at Baba's feet. In return, Baba promised not only to provide full assistance with the book but also to serve the devotee in all ways in his home, explaining that once the ego is gone, "I myself shall enter with 'I-ness' and write with my own hand."
