How was Sai Baba actually involved in the writing of his own life story? Did he just give permission, or was it more than that?

According to the text, Sai Baba's involvement was profoundly intimate, going far beyond simply granting permission. When the author expressed his desire to document Sai's life, Baba promised his full help and stated, "He is merely a pretext; I myself shall write my own story!" As detailed in Chapter 2, Sai Baba instructed the author to dissolve his ego and surrender completely at His feet. In return for this surrender, Baba promised, "I myself shall enter with 'I-ness' and write with my own hand." This indicates that Sai Baba intended to be the divine author, using the writer as a chosen instrument to fulfill the devotee's wish and narrate his own story.
