What is the author's stated purpose for writing about Sai Baba's life, and what is the spiritual benefit of engaging with these stories, according to Chapter 43?

In Chapter 43, the author, Hemad, expresses that his devotion is to Sai's feet and that Sai himself grants the devotion and love needed to write the life story. The chapter emphasizes the spiritual benefits of such engagement, stating that remembering the glory of God's devotees through bhajan or kirtan is the easiest means to wash away accumulated sins and make the inner self pure. Even though the topic of the body's end can be difficult, the text asserts that discussing the passing of saints and sages purifies both the listeners and the speakers, ultimately helping to end worldly existence.
