Based on Chapter 6, how was Sai Baba involved in the writing of the Shri Sai Satcharitra itself?

Chapter 6 reveals the author's deep conviction that Sai Baba was the true author of the Satcharitra. The author confesses that when he takes paper to write, he feels incapable of joining word to word. However, he states that Sai Baba Himself makes him write by His own divine power, making the writing seem inexhaustible. This chapter also notes that whenever the author's ego would emerge during the writing process, Sai would personally suppress it and bestow His own power, thus making the disciple fulfilled in his task.
