How does the author, Hemad, describe his own role in writing these stories and who does he credit as the true narrator?

In Chapter 47, the author, Hemad, presents himself as merely a conduit for a higher power. He goes so far as to say that "Hemad" is just a nickname and questions his own significance in the process. He explicitly states that Sai Samarth himself is the story, the speaker, and the face of the narration. According to this passage, Sai is the "eye of the eyes and the ear of the ears," and it was Sai who, by entering Hemad's heart, directly narrated the account. Hemad emphasizes that he is as empty as any listener if he fails to grasp the essential meaning of the stories he is transcribing.
