What does Sai Baba mean when he says the author is 'merely a pretext' and that He will 'write my own story'?

When Sai Baba states, "He is merely a pretext; I myself shall write my own story!" He is conveying a profound spiritual principle about divine authorship and the importance of surrendering the ego. As explained in Chapter 2, this statement means the human author's role is to become an empty vessel. By dissolving his personal ego and surrendering it completely at Baba's feet, the author allows Baba to enter with His own 'I-ness' and write the story directly. The work is accomplished by the One to whom it belongs, and the writer is simply the chosen instrument for the divine task.
