How does the author of the Sai Satcharitra portray Sai Baba's role in the creation of the book itself in Chapter 3?

In Chapter 3, the author humbly presents his role not as a creator, but as an instrument of Sai Baba's grace. He explicitly states that Sainath Himself is the true author, who "kept me in front as a pretext" to get this work done. To illustrate this point, the text in Chapter 3 uses two powerful analogies. First, Sai's love is compared to a motherly cow that naturally feels a surge of milk for her calf, showing that His grace flows spontaneously. Second, Sai is depicted as a "cloud of joy" that rains down to satisfy the thirst of the devotee, likened to a Chataka bird, demonstrating His boundless compassion in fulfilling the spiritual needs of His followers.
