Chapter 2 mentions that other books and poems about Sai Baba were already available. Could you list these specific works and their authors as described in the text?

Yes, Chapter 2 provides a list of several contemporary works that contained stories and teachings of Sai Baba. The author first highlights the contributions of Das Ganu, who wrote two significant books: Bhakta-Lilamrut and Santa-Kathamrut. It is specifically noted that Sai's life is described in three chapters of Bhakta-Lilamrut, and a specific knowledge-story is found in Chapter 57 of Santa-Kathamrut. Beyond Das Ganu's books, the text also mentions his miscellaneous poems. Other sources listed in Chapter 2 include the Bhajanmala by Raghunath-Savitri, works written with great love by Amidas and Bhavani Metha for Gujarati devotees, and a series of stories being published in Pune under the name Sai Prabha.
