How involved was Sai Baba in the writing of his own life story, according to the author?

According to the narrative in Chapter 2, Sai Baba was profoundly and directly involved in the creation of his biography. When the author sought permission to compile the stories, Baba not only gave his blessing but stated, "I myself shall write my own story!" He elaborated that the author was merely a pretext and that for a devotee who dissolves their ego and surrenders, Baba himself would enter with 'I-ness' and write with his own hand. This suggests that the work is not just a human endeavor but a divinely inspired and co-authored text, with Sai Baba as the ultimate source of the narrative.
