How does the author portray his own role and capabilities in writing the Sai Satcharitra, according to the text in Chapter 50?

Throughout Chapter 50, the author, Hemadpant, portrays his role with profound humility, consistently downplaying his own abilities. He begins by expressing gratitude for his fortunate birth but quickly pivots to his own limitations, asking, 'What power do I, a wretched one, have to describe his glory?' He asserts that the book is not a product of his own intellect or skill. Instead, as Chapter 50 clarifies, he believes that Sai Baba himself is the true author, who 'out of love for his devotees, reveals this book through grace.' Hemadpant sees himself merely as a humble instrument, reinforcing this idea with the metaphor of a plowed field that requires the 'Cloud of Grace' to rain for any crop to be produced.
