According to the author, what is the transformative power of listening to Sai's stories, and who is the true narrator?

The text from Chapter 47 explains that listening to the purifying stories of Sai Baba has profound spiritual benefits. It states that for both wise and ignorant listeners, hearing these accounts can sever the bonds of Karma and cause them to forget their bodily consciousness, becoming overwhelmed by divine love. The author, Hemad, humbly clarifies his role, stating he is merely a "nickname." He asserts that Sai Baba himself is the true source, being the story, the speaker, and the face, who enters Hemad's heart to narrate the account for the benefit of all who listen.
