How does the author, Hemad, describe his personal feelings and the purpose of writing in Chapter 43?

In Chapter 43, the author Hemad expresses profound humility and devotion. He describes himself as devoted to Sai's feet, merely sketching the life story. He believes that the love and devotion he feels are created by Sai himself, who is the Almighty. Hemad states that he cannot comprehend Sai's greatness through mere thought and instead chooses to surrender his mind. He feels that remembrance of God's devotees, through devotional singing (bhajan) or chanting (kirtan), is the most effective means to wash away sins and purify the inner self, suggesting this is the ultimate purpose of his writing.
