From the perspective of Chapter 43, what is the author's purpose in recounting the story of Sai Baba's passing?

In Chapter 43, the author, Hemad, expresses a deep sense of devotion and surrender to Sai Baba. His stated purpose is to complete the story of Baba's departure that was left incomplete in the prior chapter. He believes that telling this story is an act of devotion and that the remembrance of God's devotees is a powerful means to purify the inner self. As the chapter notes, even though the news of the body's end is not pleasing, "the passing of saints and sages purifies both the listeners and the speakers." The author sees himself as a mere instrument, stating that Baba himself creates the love and devotion required to write the life story.
