What is the author's personal reflection and purpose as stated at the beginning of Chapter 43?

At the start of Chapter 43, the author, Hemad, expresses his profound devotion and complete surrender to Shri Sai. He states that he is merely sketching Sai's life story and that the love, devotion, and even the greatness of the story itself are all granted by Sai. Hemad reflects that he cannot comprehend Sai's greatness through thought alone and instead surrenders with a focused mind. He posits that devotional practices like bhajan and kirtan, which are the remembrance of the glory of God's devotees, are the most effective means to purify the inner self and wash away accumulated sins, a path glorified by Sai himself.
