What is the philosophical message conveyed by the events surrounding the completion of the Sai Satcharitra's final chapter?

The concluding narrative in Chapter 53 delivers a strong philosophical message about the supremacy of the Guru's will over individual plans. The original author, Hemadpant, had made a promise to write a summary, but his unexpected death prevented it. This is interpreted not as a mere accident but as a divine lesson, as the text states, "Nothing happens by one's own will; Baba’s will is more powerful." Furthermore, the new author's feelings of inadequacy and their reliance on the Guru's grace reinforce this theme. They believe that Sai Baba himself is the true author, and their mouth is "merely an instrument." The entire episode serves as a practical demonstration of surrendering one's ego and acknowledging that all actions are ultimately guided by the Sadguru's power.
