How does the author describe his own role and mindset in writing the Sai Satcharitra, just before beginning Damu Anna's story?

Just before introducing Damu Anna's story in Chapter 25, the author expresses profound humility about his role in writing the book. He states that at the moment of writing, his 'meager intellect became endowed with courage and special knowledge' directly from Sai. He questions his own audacity, suggesting he would not have been capable of such a task on his own. He firmly believes that Sai Baba Himself will accept the book for the salvation of devotees and that the entire work is not a mere play of words but rather the 'nectar-like life story' which is the 'grace and "Prasad" of the Saint's feet.'
