How does the author of the Sai Satcharitra describe his own role in writing Chapter 30 and his relationship with Sai?

In Chapter 30, the author expresses deep humility regarding his role in composing the text. He questions his own qualifications, stating, 'what qualification do I have? Who takes up this task upon themselves?' He firmly believes that the work is not his own but that Sai Baba is the true orchestrator, getting the work accomplished through him. The author views himself merely as a vessel, declaring that Sai is the 'illuminator of my speech' and the 'capable lamp of knowledge' who destroys the darkness of ignorance. This complete faith in Sai as the doer stills the wavering of his mind and removes any apprehension about the task of writing.
