What is the author Hemad's stated purpose and personal perspective on writing about Sai Baba in the introduction of Chapter 43?

In the opening of Chapter 43, the author Hemad expresses his deep reverence and surrenders his ego to the task of writing Sai Baba's life story. He states that the "wonderful love" for Sai is created by the Almighty himself and that he, Hemad, is merely an instrument sketching the story. He credits Sai with granting the devotion and love required for the work and for increasing the story's greatness. Hemad also posits a spiritual purpose for the narrative, explaining that remembering the glory of God's devotees and engaging in devotional singing (bhajan) or chanting (kirtan) are the most effective means "to wash away the filth of accumulated sins" and purify the inner self.
