What was Sai Baba's direct role in the creation of his life story, and what conditions did He set for the author?

According to the narrative in Chapter 2, Sai Baba assured the author, who was initially impatient, of His full assistance in compiling a collection of His stories and experiences. Baba explicitly stated 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 set by Baba was for the author to completely dissolve his ego and surrender it at Baba's feet. As explained in Chapter 2, Baba promised that upon the dissolution of the ego, He would personally enter with 'I-ness' and write with His own hand, ensuring the work's successful completion.
