How does Hemadpant describe his own role in writing the Shri Sai Satcharitra in Chapter 50, and to whom does he attribute the true authorship?

In Chapter 50, the author, Hemadpant, expresses profound humility about his role in creating the text. He questions his own power to describe Sai's glory, referring to himself as a 'wretched one.' He firmly asserts that the book is not his own work but is being revealed through him by Sai Baba's grace, which stems from Sai's deep love for his devotees. Hemadpant uses the metaphor of a plowed field and a buried seed, explaining that without the 'Cloud of Grace' (Sai) raining upon it, no crop (the book) can be produced, thus attributing the true authorship to Sainath himself.
