What does the author of the Sai Satcharitra reveal about his personal writing process and Sai's involvement in it?

In Chapter 6, the author shares his experience of writing the holy book, emphasizing that it is not his own effort but a direct result of Sai's grace. He confesses that when he tries to write on his own, he cannot even join two words together. However, when Sai Baba Himself inspires him to write through His divine power, the words flow inexhaustibly. The chapter states that whenever the author's ego begins to surface, Sai suppresses it with His own hand and bestows His power, thus making the disciple's work fulfilled and complete.
