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

In Chapter 43, the author Hemad presents his role with great humility, viewing himself as a devoted instrument of Sai Baba. He acknowledges that the "news of the body’s end does not please anyone’s heart" and that listeners might find the topic of departure wearying. However, he justifies telling the story by asserting that "the passing of saints and sages purifies both the listeners and the speakers." As stated in Chapter 43, Hemad feels that the greatness of the life story and the devotion it inspires are granted by Sai himself. He expresses his inability to fully comprehend Sai's greatness through thought alone and instead chooses to "simply surrender to him with a focused mind," framing the act of writing as a form of devotional service.
