What is the author's stated purpose and motivation for writing Chapter 43, as described in the text?

In Chapter 43, the author, Hemad, expresses his deep devotion to Sai Baba's feet and frames the act of writing as sketching his life story. The chapter begins by stating that the wonderful love toward Sai is created by the Almighty himself, who also grants the author the devotion and love to write. Hemad's motivation, as presented in Chapter 43, is also to purify the mind, asserting that remembering the glory of God's devotees through bhajan or kirtan is the easiest means for inner purification. He sees the greatness of the life story as being increased by Sai himself, thereby giving glory to devotional practices.
