Can you explain the author's comparison of his work to that of historical writers like Mahipati and Das Ganu in Chapter 2?

In Chapter 2, the author places his own work within a tradition of divinely inspired biographical writing. He draws a parallel to Mahipati, who was inspired in the Shaka year 1700 to write the lives of saints, and to Das Ganu, who performed a similar service in the Shaka year 1800. Just as saints took service from them, the author believes Sai Baba is working through him, an 'ignorant person,' to write his own story. The author mentions Das Ganu's two books, 'Bhakta-Lilamrut' and 'Santa-Kathamrut,' noting that the former contains three chapters on Sai's life, thus positioning his own comprehensive work as a continuation of this sacred tradition.
