What does Hemad, the author, reveal in Chapter 43 about the inspiration and purpose behind writing Sai Baba's life story?

In the introduction of Chapter 43, the author Hemad expresses that his work is inspired and guided by Sai Baba himself. He writes that the "wonderful love" for Sai is a creation of the Almighty and that he, as an author devoted to Sai's feet, is merely sketching the life story. Hemad states that Sai Baba alone "grants devotion and love" and "increases the greatness of this life story." The ultimate purpose, as described in Chapter 43, is that through this devotional act, "worldly existence comes to an end" for the devotee. The author acknowledges his own limitations, stating he cannot grasp Sai's greatness through thought alone and simply surrenders to him.
