Chapter 2 mentions other authors who wrote about Sai Baba. Who were they, and how did the author justify writing yet another book?

Chapter 2 acknowledges several existing works about Sai Baba. It names Das Ganu as the author of 'Bhakta-Lilamrut' and 'Santa-Kathamrut,' noting that the former contains three chapters on Sai's life. It also mentions Raghunath-Savitri’s 'Bhajanmala,' miscellaneous poems by Das Ganu, writings for Gujarati devotees by Amidas and Bhavani Metha, and a series of stories published in Pune under the name 'Sai Prabha.' When addressing the need for a new book, the author uses an analogy, comparing Sai's life to a vast, infinite ocean. As stated in Chapter 2, the author feels like a small Titwi bird attempting the impossible task of emptying this ocean. Therefore, the justification is that since Sai's stories are infinite, any collection is valuable, and one should find satisfaction in whatever can be shared.
