What is the concluding message of Chapter 53, and who was ultimately responsible for writing it according to the author?

The concluding message of Chapter 53 is one of profound surrender and faith in the Guru's grace. The chapter explains that the original author, Hemadpant, passed away before he could write the promised summary. The new author feels completely inadequate for the task, describing themselves as a 'fool with a dull intellect.' However, the core message, as stated in Chapter 53, is that nothing happens by one's own will and that 'Baba’s will is more powerful.' The author concludes that Sai Baba himself, the 'breaker of obstacles (Vakratunda),' will be the one to write the summary, with the writer's mouth serving merely as an instrument for the Guru's work.
