How was Sai Baba involved in the writing of his life story?

Sai Baba was not just a subject but an active participant in the creation of his life story. According to Chapter 2, when the author considered compiling a collection of stories and experiences, Sai Baba offered his full support and compassion. More profoundly, Baba stated, "He is merely a pretext; I myself shall write my own story!" This implies that Baba saw himself as the true author, working through the devotee. He promised to give his full assistance and even serve in the author's home, provided the author dissolved his ego and surrendered completely at Baba's feet.
