What were Sai Baba's specific instructions and conditions for allowing his life story to be written?

According to Chapter 2, when granting permission to write his stories, Sai Baba offered his full support with a significant condition. He stated that the author was to be "merely a pretext," as He Himself would write His own story. The critical requirement for receiving this divine assistance was that the author must dissolve his ego and surrender it completely at Baba's feet. Sai Baba promised that for anyone who successfully does this, He would not only assist with the book but would "serve in all ways in his home." The process was to begin with the thought that the work truly belongs to the One accomplishing it.
