What does the final chapter of the Sai Satcharitra say about the role of divine will and a Guru's grace?

Chapter 53 places a strong emphasis on the power of divine will and the indispensability of a Guru's grace. It posits that Hemadpant's failure to complete the book was not a personal failing but an instance of Baba's will being 'more powerful' than human plans. The new author who takes up the task embodies complete surrender. He describes himself as a 'fool with a dull intellect' and believes he has no capacity to compose poetry on his own. His only hope, as he repeatedly states, is the grace of the Guru, Shri Dattaguru and Sai. He prays for them to inspire his mind, believing their power is so great it can 'make a gnat lift a mountain,' and that Sai himself will be the true author of the summary.
