How does the author, Hemadpant, portray his own role in narrating the stories of Sai Baba?

In Chapter 47, the author, Hemadpant, presents himself as merely a humble instrument for Sai Baba's teachings. He states that Sai himself is the story, the speaker, and the face, questioning his own identity by saying, 'who is Hemad? He is merely a nickname.' He emphasizes that Sai, the eye of the eyes, entered his heart and narrated the account himself. Hemadpant clarifies that while he is the speaker, he is as empty as the listeners if he doesn't grasp the essence of the story, highlighting that the true source of the narrative is Sai Samarth.
