How does the author of the Sai Satcharitra, Hemadpant, describe his own role in composing the text in Chapter 30?

In Chapter 30, the author expresses deep humility about writing the Sai Satcharitra, viewing himself as merely an instrument of Sai Baba. He questions his own qualifications, stating, 'what qualification do I have?' and posits that the work is being accomplished by Sai Baba Himself. Hemadpant describes Sai as the 'illuminator of my speech' and the 'capable lamp of knowledge' who destroys the darkness of ignorance. This complete faith in Sai as the true doer is why the author feels no burden or apprehension in undertaking the task, believing the responsibility lies entirely with his Guru.
