Chapter 2 mentions other authors who wrote about Sai Baba before the Sai Satcharitra. Who were they and what were their works?

Chapter 2 acknowledges several prior works about Sai Baba. It specifically mentions Das Ganu, who was inspired in the year 1800 (Shaka) to write two books: Bhakta-Lilamrut and Santa-Kathamrut. The life of Shri Sai is described in three chapters of the former, and a knowledge-story told by Sai is in Chapter 57 of the latter. As noted in Chapter 2, the text also refers to Gujarati books by devotees Amidas and Bhavani Metha, miscellaneous poems by Das Ganu, Raghunath-Savitri’s Bhajanmala, and a series of stories called Sai Prabha published in Pune, highlighting the existing body of literature on Sai Baba.
