Who does Sai Baba say is actually responsible for writing the stories of his life?

According to the text, Sai Baba explains that the human author is merely a pretext for the work. As detailed in Chapter 2, Sai Baba felt compassion for the devotee's desire to document his stories and stated, "He is merely a pretext; I myself shall write my own story! I should tell my own story and fulfill the devotee's wish." He elaborates that once a devotee dissolves their ego and surrenders it at his feet, He himself will enter with 'I-ness' and write with his own hand, providing full assistance and service to the devotee.
