What is the author Hemad's stated purpose and perspective in writing Chapter 43?

In Chapter 43, the author Hemad expresses his deep devotion to Sai Baba. He states that he is merely "sketching his life story" and that it is Sai himself, the Almighty, who creates the wonderful love and devotion in the author's heart. Hemad attributes the greatness of the life story and the glory of devotional singing to Sai. He emphasizes that listening to the glory of God's devotees is an easy means to purify the mind and wash away accumulated sins. Therefore, as stated in Chapter 43, his purpose is to complete the story of Sai's passing, which he believes purifies both the listener and the speaker.
